This document describes enhancements to Transparent Common-Channel Signaling (CCS) and frame forwarding for the Cisco MC3810 multiservice access concentrator and includes the following sections:
The Transparent CCS (T-CCS) feature provides a way to interconnect private branch exchanges (PBXs), key systems (KTs), and central office switches (COs) when the private integrated services network exchange (PINX) does not support QSIG, or when the PINX uses a proprietary solution. Transparent CCS allows the connection of two PBXs with PRI or BRI interfaces that use one CCS protocol without the need for interpretation of CCS signaling for call processing. A PBX PRI group is transported transparently through the data network and the feature preserves proprietary signaling. From the PBX standpoint, this is accomplished through a point-to-point connection. Calls from the PINXs are not routed, but follow a preconfigured route to the destination. Transparent CCS is implemented in two ways:
Transparent CCS provides the following benefits:
The following restrictions apply:
CCS differs from a related technology, channel-associated signaling (CAS) in that it uses a separate transmission channel to relay signaling and address information in embedded packets conforming to standards recommendations. Examples of CCS signaling include Q.931 on ISDN Primary Rate Interface (PRI) and QSIG protocol signaling for PINX devices.
CAS signaling, which is older than CCS, has evolved over many years and is supported on many Cisco routers. CAS signals and the DTMF (or Dial pulse) digits that indicate the called party's telephone number are presented within the actual voice band transmission channel. Digital Signal processors (DSPs) in Cisco voice nodes monitor these channels, decode the status and address signaling, and report status and state changes for the telephone calls.
The following documents can help you understand Transparent CCS support and related technologies:

None.
Perform the following tasks to configure your Cisco MC3810 multiservice concentrator:
This section is divided into the following procedures for CCS Cross-Connect:
When you configure CCS cross-connect for E1 or T1, you set up time slot groups, then configure cross-connect from the first T1/E1 controller to the second T1/E1 controller. The mode ccs cross-connect command allows the cross-connect. This enables all the channels to perform similarly to normal CAS mode, except that the signaling bit is no longer processed by the router.
To configure Transparent CCS cross-connect, complete the following steps beginning in global configuration mode:
Step 1 | router# controller T1 | E1 0 | Enter controller configuration mode for controller E1 or T1 0. |
Step 2 | router(config-controller)# tdm-group tdm-group-no | Configure a TDM channel group. Do not specify the type option in the command. Valid values for tdm-group-no are 0 through 23 for T1 and 0 through 30 for E1. The valid timeslots values are: 1 to 24 for T1; 1 to 15 and 17 to 31 for E1. You can enter ranges or individual time slot numbers. |
Step 3 | router(config-controller)# exit | Exit controller configuration mode for this controller. |
Step 4 | router# controller T1 | E1 1 | Enter controller configuration mode for controller E1 or T1 1. |
Step 5 | router(config-controller)# mode ccs cross-connect | Configure the controller to support CCS cross-connect and trigger the signaling channel. |
Step 6 | router(config-controller)# tdm-group tdm-group-no | (T1 only) Configure a second TDM channel group. Do not specify the type option in the command. Valid values for tdm-group-no are 0 through 23 for T1 and 0 through 30 for E1. The valid timeslots values are: 1 to 24 for T1 and 1 to 15 and 17 to 31 for E1. You can enter ranges or individual time slot numbers. |
Step 7 | router(config-controller)# | (E1 only) Configure the specified channel to support CCS mode. Valid values for channel-no are 0 through 23 for T1 and 0 through 30 for E1. The valid timeslots values are: 1 to 24 for T1 and 1 to 31 for E1. You can enter ranges or individual time slot numbers. Specify ext-sig as the type for FRF.11 support. This option is available only when the mode ccs cross-connect command is enabled. Note The ds0-group command replaces the voice-group command that was supported in earlier releases. ext-sig replaces the ext-sig-master and ext-sig-slave options that were supported with the voice-group command. |
Step 8 | router(config-controller)# | Configure cross-connect pass-through between the two controllers. Depending on whether you are using T1 or E1, connect the two TDM controller groups (T1) or connect the TDM group controller to the DS0 group controller (E1). |
 | Tips After you configure a Transparent CCS connection by entering the connection trunk command, no change to the configuration takes place until the connection is shut down with a shutdown command and then restarted with a no shutdown command. For example, the phone number supplied in the connection trunk command can be changed while the connection is in no shutdown state, but the change will not cause the current connection to be closed and a new connection to be opened to the new phone number. This will only take effect on the next no shutdown command following a shutdown command. |
To use CCS cross-connect for bearer channels of the E1 or T1 trunk, you must perform the following additional configuration beginning in global configuration mode:
Step 1 | router# controller {T1 | E1} number
| Enter controller configuration mode for the controller. |
Step 2 | router(config-controller)# | Specify the controller to support CCS cross-connect. This option automatically creates serial interface 1:15 (E1) or 1:23 (T1) |
Step 3 | router(config-controller)# | Configure the specified channel to support CCS mode. Valid values for channel-no are 0 through 23 for T1 and 0 through 30 for E1. The valid timeslots values are: 1 to 24 for T1 and 1 to 31 for E1. You can enter ranges or individual time slot numbers. Specify ext-sig as the type for FRF.11 support. This option is available only when the mode ccs cross-connect command is enabled. The ds0-group command replaces the voice-group command that was supported in earlier releases. ext-sig replaces the ext-sig-master and ext-sig-slave options that were supported with the voice-group command. |
Step 4 | router(config-controller)# exit | Exit controller configuration mode for this controller. |
Step 5 | router# (config-if)# voice-port slot/port | Enter voice-port configuration mode. For digital voice ports, the slot number is 1 for this configuration. Valid numbers for port are from 1 to 24 for T1, from 1 to 15, or from 17 to 31 for E1. Note The slot:port format is also accepted. |
Step 6 | router# (config-voiceport)# connection trunk string | Configure the voice-port connection. For the string, enter the number of the voice channel that was configured as the ext-sig type for the ds0-group command. |
To configure CCS frame-forwarding, follow these steps beginning in global configuration mode:
Step 1 | router# controller {T1 | E1} 1
| Enter controller configuration mode. CCS frame-forwarding is only available on controller T1 1 or E1 1. |
Step 2 | router# (config-controller)# mode ccs frame-forwarding | Specify the controller to support CCS frame-forwarding. |
Step 3 | router(config-controller)# | Configure the specified channel to support CCS mode. Valid values for channel-no are 0 through 23 for T1 and 0 through 30 for E1. The valid timeslots values are: 1 to 24 for T1 and 1 to 31 for E1. You can enter ranges or individual time slot numbers. Specify ext-sig as the type for FRF.11 support. This option is available only when the mode ccs frame forwarding command is enabled. The ds0-group command replaces the voice-group command that was supported in earlier releases. ext-sig replaces the ext-sig-master and ext-sig-slave options that were supported with the voice-group command. |
Step 4 | router# (config-controller)# exit | Exit controller configuration mode. |
Step 5 | router# (config-if)# voice-port slot/port | Enter voice-port configuration mode. For digital voice ports, the slot number is always 1. Valid numbers for port are from 0 to 23 for T1, from 0 to 15, or from 17 to 30 for E1. Note The slot:port format is also accepted. |
Step 6 | router(config-voiceport)# connection trunk string | For the string, enter the number of the voice channel that was configured as the ext-sig type for the ds0-group command. |
Step 7 | router(config-voiceport)# exit | Exit voice-port configuration mode. |
Step 8 | router (config-if)# interface serial 1:x | Enter interface mode for serial 1:x where x represents the channel number. For E1, enter 15 (the actual signaling channel is 16). For T1, enter 23 (the actual signaling channel is 24). This procedure maps the D channel from the DVM to the specified interface. |
Step 9 | router (config-if)# ccs encap frf11 | (Frame Relay only) This command allows you to specify the standard Annex-C format. Use this command to define the packet format for the CCS packet; it places the FRF.11 Annex-C (Data Transfer Syntax) standard header on the CCS packets only and not on B channel packets. Once this command is executed, you can use the ccs connect command to specify a CID other than 254. |
Step 10 | router (config-if)# ccs connect {serial |atm } number | (Frame Relay and ATM) Configure the CCS connection. If the CCS connection is over Frame Relay, specify a serial interface and the DLCI. If the CCS connection is over ATM, specify atm, interface 0, and the PVC. The cid option allows you to specify a channel identifier (CID) from 5 to 255. If you have not executed the ccs encap frf11 command, however, any CID number other than the default of 254 is ignored, and Cisco encapsulation is used. |
Step 11 | router (config-if)# no cdp enable | Disable Cisco Discovery Protocol (CDP) on the interface. Note CDP and keepalives are disabled by default on a D channel interface. |
Step 12 | router (config-if)# no keepalive | Disable keepalive packets on the interface. |
Step 1 To see information about voice-port configuration, enter the show voice port summary command.

The following new or modified commands are used to configure the Transparent CCS and CCS frame forwarding features. All other commands used with this feature are documented in Cisco IOS 12.0 command references and on CCO. See "Related Documents".
To configure a CCS connection on an interface configured to support CCS frame forwarding, use the ccs connect interface configuration command. To disable the CCS connection on the interface, use the no form of this command.
ccs connect {serial | atm} number [ dlci | pvc vpi/vci | pvc name ] [ cidnumber ]
number | Specify the connection number. |
The following parameters are used for Frame Relay configuration:
serial | Make a serial CCS connection. |
dlci | Specify the DLCI number. |
cidnumber | (Optional) If you have executed the ccs encap frf11 command, the cid option allows you to specify any CID number from 5 to 255. |
atm | Make an ATM CCS connection. |
pvc vpi/vci | Specify the PVC virtual path identifier/virtual channel identifier. Acceptable values are from 0 to 255; the slash is required. |
pvc name | Specify the PVC string that names the PVC for recognition. |
No CCS connection is made.
Serial interface configuration mode
| Release | Modification |
|---|---|
Cisco IOS Release 12.0(2)T | This command was introduced for the Cisco MC3810. |
Cisco IOS Release 12.0(7)XK | Added CID syntax, removed dlci keyword and vcd options. |
Use this command to configure a CCS connection. If the CCS connection is over Frame Relay, specify a serial interface and the DLCI. If the CCS connection is over ATM, specify atm, the interface number (0 only on the Cisco MC3810), and the PVC.
If you have executed the ccs encap frf11 command, the cidnumber option allows you to specify any CID from 5 to 255. If you do not issue the ccs encap frf11 command, Cisco encapsulation is used, and any CID value other than 254 is ignored.
To configure a frame relay CCS frame-forwarding connection on DLCI 100 by using the default CID of 254, enter the following command:
ccs connect serial 1 100
or:
ccs connect serial 1 100 10
To configure a CCS frame-forwarding connection over an ATM PVC, enter the following command:
ccs connect atm0 pvc 100/10
or:
ccs connect atm0 pvc 10/100 21
or:
ccs connect atm0 pvc mypvc_10 21
To configure a Frame Relay CCS frame-forwarding connection on DLCI 100 using a CID of 110, enter the following command:
ccs connect serial 1 100 110
| Command | Description |
|---|---|
ccs encap frf11 | Allows the specification of the standard Annex-C FRF.11 format. |
To configure the common channel signaling (CCS) packet encapsulation format for FRF.11, use the ccs encap frf11 command. Use the no form of this command to disable ccs encapsulation for FRF11.
ccs encap frf11There are no keywords or arguments.
By default, the format is a Cisco packet format, using a channel ID (CID) of 254.
Serial configuration mode
| Release | Modification |
|---|---|
Cisco IOS Release 12.0(7)XK | This command was introduced for the Cisco MC3810. |
This command allows the specification of the standard Annex-C format. Use this command to define the packet format for the CCS packet; it places the FRF.11 Annex-C (Data Transfer Syntax) standard header on the CCS packets only.
Once the ccs encap frf11 command is executed, you can use the ccs connect command to specify a CID other than 254.
The following example shows how to configure a serial interface for Frame Relay:
router(config)# interface Serial1:15 router(config-if)# ccs encap frf11 router(config-if)# ccs connect Serial0 990 100
| Command | Description |
|---|---|
mode ccs frame-forwarding | Set to forward frames on the controller. |
To specify the DS0 timeslots that make up a logical voice port on a T1 or E1 controller, and to specify the signaling type, use the ds0-group controller configuration command. Use the no form of the command to remove the DS0 group and signaling setting.
ds0-group ds0-group-no timeslots timeslot-list type signal-type
no ds0-group ds0-group-no
ds0-group-no | A value from 0 to 23 that identifies the DS0 group. |
timeslot-list | timeslot-list is a single timeslot number, a single range of numbers, or multiple ranges of numbers separated by commas. For T1, allowable values are from 1 to 24. Examples are: · 2 · 1-15, 17-24 · 1-23 · 2, 4, 6-12 |
type | The signaling method selection for type depends on the connection that you are making. The E&M interface allows connection for PBX trunk lines (tie- lines) and telephone equipment. The FXS interface allows connection of basic telephone equipment and PBXs. The FXO interface is for connecting the central office (CO) to a standard PBX interface where permitted by local regulations. The FXO interface is often used for off-premises extensions. The options are as follows: · e&m-immediate-start---no specific off-hook and on-hook signaling · e&m-delay-dial---the originating endpoint sends an off-hook signal and then waits for an off-hook signal followed by an on-hook signal from the destination · e&m-wink-start---the originating endpoint sends an off-hook signal and waits for a wink signal from the destination · fxs-ground-start---Foreign Exchange Station ground-start signaling support · fxs-loop-start ---Foreign Exchange Station loop-start signaling support · fxo-ground-start---Foreign Exchange Office ground-start signaling support · fxo-loop-start---Foreign Exchange Office loop-start signaling support |
| The following options are available only on E1 controllers on the Cisco MC3810: · e&m-melcas-immed---E&M Mercury Exchange Limited Channel Associated Signaling (MELCAS) immediate start signaling support · e&m-melcas-wink---E&M MELCAS wink start signaling support · e&m-melcas-delay---E&M MELCAS delay start signaling support · fxo-melcas---MELCAS Foreign Exchange Office signaling support · fxs-melcas---MELCAS Foreign Exchange Station signaling support |
| The ext-sig option is available only when the mode ccs command is enabled on the Cisco MC3810 for FRF.11 transparent CCS support. |
No DS0 group is defined.
Controller configuration
| Release | Modification |
|---|---|
11.2 | This command was introduced for the Cisco AS5300 as cas-group. |
12.0(1)T | The cas-group command was first supported on the Cisco 3600 series. |
12.0(5)T | This command was renamed ds0-group on the Cisco AS5300 and on the Cisco 2600 and 3600 series (requires Digital T1 Packet Voice Trunk Network Modules). |
12.0(7)XK | Support for this command was extended to the Cisco MC3810. When the ds0-group command became available on the Cisco MC3810, the voice-group command was removed and no longer supported. ext-sig replaces the ext-sig-master and ext-sig-slave options that were available with the voice-group command. |
The ds0-group command automatically creates a logical voice port that is numbered as follows:
Cisco 2600 and 3600 series:
slot/port:ds0-group-no.
Cisco MC3810:
slot:ds0-group-no
On the Cisco MC3810, the slot number is the controller number. Although only one voice port is created for each group, applicable calls are routed to any channel in the group.
The following example configures ranges of T1 controller timeslots for FXS ground-start and FXO loop-start signaling on a Cisco 2600 or 3600 Series router:
router(config)# controller T1 1/0 router(config-controller)# framing esf router(config-controller)# linecode b8zs router(config-controller)# ds0-group 1 timeslot 1-10 type fxs-ground-start router(config-controller)# ds0-group 2 timeslot 11-24 type fxo-loop-start
The following example configures DS0 groups 1 and 2 on controller T1 1 on the Cisco MC3810 to support Transparent CCS:
router(config)#controller T1 1router(config-controller)#mode ccs cross-connectrouter(config-controller)#ds0-group 1 timeslot 1-10 type ext-sigrouter(config-controller)#ds0-group 2 timeslot 11-24 type ext-sig
| Command | Description |
codec complexity | Matches the DSP complexity packaging to the codec(s) to be supported |
mode ccs | Configures the T1/E1 controller to support CCS cross-connect or CCS frame-forwarding. |

AAL---ATM Adaptation Layer. Service-dependent sublayer of the data link layer. The AAL accepts data from different applications and presents it to the ATM layer in the form of 48-byte ATM payload segments. AALs consist of two sublayers: convergence sublayer (CS) and segmentation and reassembly (SAR). AALs differ on the basis of the source-destination timing used, whether they use constant bit rate (CBR) or variable bit rate (VBR), and whether they are used for connection-oriented or connectionless mode data transfer. At present, the four types of AAL recommended by the ITU-T are AAL1, AAL2, AAL3/4, and AAL5.
ATM---Asynchronous Transfer Mode. International standard for cell relay in which multiple service types (such as voice, video, or data) are conveyed in fixed-length (53-byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media, such as E3, SONET, and T3.
CAS---channel-associated signaling. Trunk signaling (for example, in a T1 line) in which control signals, such as those for synchronizing and bounding frames, are carried in the same channel along with voice and data signals.
CBR---constant bit rate. QoS class defined by the ATM Forum for ATM networks. CBR is used for connections that depend on precise clocking to ensure undistorted delivery.
CCS---common channel signaling. Trunk signaling (for example, using Primary Rate Interface) in which a control channel carries signaling for separate voice and data channels.
CES---circuit emulation service. Enables users to multiplex or concentrate multiple circuit emulation streams for voice and video with packet data on a single high-speed ATM link without a separate ATM access multiplexer.
CO---central office. Local telephone company office to which all local loops in a given area connect and in which circuit switching of subscriber lines occurs.
codec---coder-decoder. Device that typically uses pulse code modulation to transform analog signals into a digital bit stream and digital signals back into analog.
DSP---digital signal processor; same as PVDM
DVM---Digital Voice Module
E1---European digital carrier facility used for transmitting data through the telephone hierarchy. The transmission rate for E1 is 2.048 megabits per second (Mbps).
E&M---rEceive and transMit, or Ear and Mouth. Type of signaling originally developed for analog two-state voltage telephony using the ear and mouth leads; in digital telephony, uses two bits.
ESF---Extended Superframe. Framing type used on T1 circuits that consists of 24 frames of 192 bits each with the 193rd bit providing timing and other functions. ESF is an enhanced version of SF format.
FXO---Foreign Exchange Office. A voice interface emulating a PBX trunk line to a switch or telephone equipment to a PBX extension interface.
FXS---Foreign Exchange Station. A voice interface for connecting telephone equipment, emulates the extension interface of a PBX or the subscriber interface for a switch.
ISDN---Integrated Services Digital Network. Communication protocol, offered by telephone companies, that permits telephone networks to carry data, voice, and other source traffic.
packet---Logical grouping of information that includes a header containing control information and (usually) user data. Packets are most often used to refer to network layer units of data.
POTS---plain old telephone service.
PSTN---Public Switched Telephone Network. General term referring to the variety of telephone networks and services in place worldwide.
QoS---quality of service. Measure of performance for a transmission system that reflects its transmission quality and service availability.
QSIG---Q (point of the ISDN model) Signaling. Signaling standard. Common channel signaling protocol based on ISDN Q.931 standards and used by many digital PBXs.
T1---Digital WAN carrier facility. T1 transmits DS 1-formatted data at 1.544 Mbps through the telephone switching network, by using alternate mark inversion or B8ZS coding.
T1 trunk---Digital WAN carrier facility. See T1.
T-CCS---Transparent Common Channel Signaling.
TDM---time-division multiplexing.
Trunk---Physical and logical connection between two switches across which network traffic travels. A backbone is composed of a number of trunks.
VAD---voice activity detection.
VoFR---voice over Frame Relay.
VoATM---voice over ATM
