Identifying Cable Types

8-Conductor Rollover Cable

Hold the connectors side-by-side, with the tab at the back. The colored wires are in the opposite sequence at opposite ends of the cable. If your cable came from Cisco Systems, pin 1 is white on one plug, and pin 8 is white on the opposite plug. (A rollover cable reverses the wire connections at the opposite ends:
1 to 8, 2 to 7, 3 to 6, 4 to 5, 5 to 4, 6 to 3, 7 to 2, and 8 to 1.)

8-Conductor Straight-Through Cable

Hold the connectors side-by-side, with the tab at the back. The colored wires are in the same sequence at opposite ends of the cable. (A straight-through cable connects like-numbered pins at opposite ends: 1 to 1, 2 to 2, 3 to 3, 4 to 4, 5 to 5, 6 to 6, 7 to 7, and 8 to 8.)

RJ-48 T1/E1 Cable

View the connector for the Cisco MC3810 port, with the tab at the back. There are wires attached to four of the pins: 1, 2, 4, and 5. (The pinout at the opposite end depends on the interface at that end.)

dial-type {pulse | dtmf}

Change the transmit dial type if necessary (FXO and E&M ports only). The default is dtmf.

Only FXO and FXS ports transmit dial pulses.

    8 

router(config-voiceport)# 
compand-type {u-law | a-law}

Change the companding if necessary. The default is u-law (the North American mu-law ITU-T PCM encoding standard). Specify a-law to use the European a-law ITU-T PCM encoding standard.

router(config-voiceport)# 
no shutdown

Activate the voice port. You should activate only those voice ports you are planning to use.

    10

Exit from voice-port configuration mode and repeat Steps 6 through 9 for the remaining digital voice ports.

Note If you are not going to use a voice port, shut it down to conserve bandwidth.

To configure voice-port tuning options, see the section "Configuring Voice-Port Tuning Options" in the "Configuring Voice Ports" chapter of the Cisco MC3810 Multiservice Access Concentrators Software Configuration Guide.

To configure dial peers, see the applicable voice service configuration section in the Cisco MC3810 Multiservice Access Concentrators Software Configuration Guide.

Configuring ISDN BRI Voice Ports

To configure the basic ISDN BRI voice-port settings, perform the following tasks:
Step Command Purpose

    1 

router> configure terminal

Enter global configuration mode.

    2 

router(config)# 
isdn switch-type basic-qsig

Configure the global ISDN switch type as basic-qsig for the BRI voice ports.

Note You can configure the ISDN switch type in either global or interface configuration mode. If you configure it here in Step 2, it specifies the switch type for all four BVM ports. If you configure it in Step 4, it specifies the switch type for a single interface. The switch type specified in Step 4 for any individual interface will override the globally specified switch type. 
router(config)# 
interface bri number

Enter interface configuration mode to configure parameters for the specified BRI voice port. The number can be from 1 to 4.

    4 

router(config-interface bri 1)# 
isdn switch-type basic-qsig

If the service provider switch type for this BRI port is different from the global ISDN switch type, configure the interface ISDN switch type to match the service provider switch type. The interface ISDN switch type overrides the global ISDN switch type on this interface.

    5 

router(config-interface bri 1)# 
isdn protocol-emulate {user |
network}

Configure the Layer 2 and Layer 3 port protocol emulation:

  • Enter user to configure the port as TE. This is the default.

  • Enter network to configure the port as NT.

Note The term user is equivalent to the QSIG term slave. The term network is equivalent to the QSIG term master.

    6 

router(config-interface bri 1)# 
isdn layer1-emulate {user | network}

Configure the Layer 1 port mode emulation and the clock settings:

  • Enter user to configure the port as TE and to function as a clock slave. This is the default.

  • Enter network to configure the port as NT and to function as a clock master.

    7 

router(config-interface bri 1)# 
[no] line-power

Turn on or off the power supplied from an NT-configured port to a TE device. The default is no line-power.

    8 

router(config-interface bri 1)# 
network-clock-priority {low | high}

If this BRI voice port is configured as TE, and you want it to act as a clock slave and recover clock from the network NT device, set it to high.

If this BRI voice port is configured as TE, and you do not want it to recover clock from the network NT device, set it to low.

This command is not used if this port is configured as NT with the command isdn layer1-emulate network.



Perform Initial Configuration (continued)

Step Command Purpose

    9 

router(config-interface bri 1)# 
isdn overlap-receiving

Activate overlap signaling to the destination PBX.

    10 

router(config-interface bri 1)# 
isdn network-failure-cause 
cause code

Specify the cause code to pass to the PBX when a call cannot be placed or completed because of internal network failures. Possible values are from 1 to 127.

router(config-interface bri 1)# 
isdn sending-complete

(Optional) Configure the BRI voice port to include the Sending Complete information element in the outgoing call setup message. This command is used in some geographic locations, such as Hong Kong and Taiwan, where the Sending Complete information element is required in the outgoing call setup message.

    12

Exit from interface configuration mode and repeat Steps 3 through 11 for the remaining BRI voice ports.

Verifying Your BRI Voice-Port Configuration

You can test your BRI voice-port configuration by doing the following:

To configure dial peers, see the applicable voice service configuration section in the Cisco MC3810 Multiservice Access Concentrators Software Configuration Guide.
