This chapter describes cabling and configuration procedures for the LightStream 1010 ATM switch circuit emulation service (CES) T1 and E1 port adapter modules (PAMs). When your switch leaves the factory, it is configured as specified in your order and is ready for installation and startup. As your communication requirements change, you might want to upgrade your system, add components, or change the initial configuration.
The following CES T1 and E1 PAMs are described in this chapter:
Software and upgrades require specific document part numbers and other frequently updated information; therefore, only basic software configuration guidelines are included in this publication. Detailed, up-to-date instructions are included in the LightStream 1010 ATM Switch Software Configuration Guide. Command-line interface (CLI) descriptions are provided in the LightStream 1010 ATM Switch Command Reference publication.
This chapter contains the following sections:
The port adapter Model WAI-T1C-4RJ48 used in the ATM/LAN switch complies with
Part 68 of the FCC rules. On the bottom of this equipment is a label that contains, among other information, the FCC registration number. If requested, this information must be provided to the telephone company.
This equipment cannot be used on telephone company-provided coin services. Connection to the Party Line Service is subject to state tariffs.
If this equipment causes harm to the telephone network, the telephone company notifies you in advance that temporary discontinuance of service might be required. If advance notice is not practical, the telephone company notifies you as soon as possible. Also, you are advised of your right to file a complaint with the FCC if you believe it is necessary.
The telephone company can make changes in its facilities, equipment, operations, or procedures that might affect the operation of the equipment. If this happens, the telephone company provides advance notice in order for you to make the necessary modifications to maintain uninterrupted service.
If trouble is experienced with this equipment, please contact us for repair and warranty information. If the trouble is causing harm to the telephone network, the telephone company can request you remove the equipment from the network until the problem is resolved.
We recommend that the customer install an AC surge arrestor in the AC outlet to which this device is connected. This is to avoid damaging the equipment caused by local lightning strikes and other electrical surges.
This equipment uses Uniform Service Order Code (USOC) jacks as listed in Table 7-1

The CES T1 and E1 PAMs (see Figure 7-1) are used for links that require constant bit rate (CBR) services such as interconnecting PBXs, time-division multiplexers, and video conference equipment over campus, public, or private networks. The four ports on the PAM can be configured as redundant links using the switch routing protocols. The T1 PAMs support unshielded twisted-pair (UTP) connectors and the E1 PAMs support either twisted-pair, shielded twisted-pair (STP), or 75-ohm BNC connectors. Status and carrier detect LEDs on each port give quick, visual indications of port status and operation. For detailed network management support, comprehensive statistics gathering and alarm monitoring capabilities are provided.
Each port on the PAM can be configured to support the following clocking options:
The LightStream 1010 switch powers up automatically. All configuration information for PAMs is saved between hot swaps and switch reboots, while interface types are discovered automatically by the switch. This eliminates mandatory manual configuration.
The LightStream 1010 supports any PAM combination. You can configure your switches with only the number and type of interfaces required, with up to 32 CES T1 or CES E1 interface ports.
The CES T1 and E1 PAMs have four ports and are ideal for intercampus or wide-area links. Figure 7-2 is an example of the CES T1 and CES E1 PAM applications.
The CES T1 or CES E1 PAM provides the following ATM connections:
All CES interfaces are bidirectional. You must use the appropriate CES interface cable to connect the CES BNC or twisted-pair PAM interface with an external CES network.
This section describes the CES connection equipment and PAM network connections
and LEDs.
For CES traffic over twisted-pair, use the RJ-48C connect or connect the CES T1 PAM or CES E1 PAM to the external CES network. See the section "ATM Connection Equipment" in the chapter "Installing the LightStream 1010 ATM Switch PAMs" for a description of an RJ-48C connector and twisted-pair and shielded twisted-pair cable.
For coaxial traffic, use the BNC connector to connect the CES E1 PAM with the external CES network. See the section "ATM Connection Equipment" in the chapter "Installing the LightStream 1010 ATM Switch PAMs" for a description of a BNC connector and coaxial cable.
The CES T1 and CES E1 PAMs provide an interface to CES switching fabrics for transmitting and receiving data at up to 1.544 Mbps (T1) and 2.048 Mbps (E1) bidirectionally. The PAM LEDs provide status information for the individual interface connections.
 | Caution T1 and E1 ports must be connected to an NT1 device. |
The CES PAM can support interfaces that connect to the following physical layers:
Connect the CES interface cables as shown in Figure 7-3.
The LEDs on the faceplate of the CES modules provide status information for the PAMs individual BNC and twisted-pair interface connections. The LEDs are shown in Figure 7-3.
The LEDs for the CES T1 and CES E1 modules show the illumination states described in Table 7-2.
| Port LEDs | Illumination States |
|---|---|
Steady green, red, or yellow; flashing green, red, or yellow; or off. | |
Steady green, red, or yellow; flashing green, red, or yellow; or off. | |
Either on (green) or off. |
Table 7-3 shows the possible status conditions of a CES T1or CES E1 port, as indicated by certain settings of associated port LEDs.
| Port Status Indication | S1 LED State | S2 LED State | CD LED State |
|---|---|---|---|
Port not configured | Off | Off | Off |
Port administratively down | Off | Off | Off |
Normal | Green | Green | Green |
Red alarm due to framing error | Red | Red | Off |
Red alarm due to loss of cells | Red | Red | Green |
Yellow alarm | Yellow | Off | Green |
Blue alarm | Off | Yellow | Green |
Port in loop state | Flashing green | Flashing green | Green |
When the switch is powered on without any previous configuration data, the ATM interfaces are automatically configured on the physical ports. ILMI and the physical card type are used to automatically derive the ATM interface type, UNI version, maximum VPI and VCI bits, ATM interface side, and ATM UNI type.
If the Interim Local Management Interface (ILMI) is disabled or if the connecting end node is not supporting ILMI, the following defaults are assigned to all CES T1 and CES E1 interfaces:
The following PAM types have specific defaults assigned:
CES T1 PAM:
CES E1 PAM:
The following defaults apply for all versions of the CES modules, unless you change them manually with specific CLI commands during module configuration:
