About the Cisco SM-X-1T3/E3 Enhanced Service Module

The Cisco SM-X-1T3/E3 1-port T3/E3 enhanced service module (SM-X) is a software-configurable T3/E3 product for Second Generation Integrated Services Routers (ISR G2) and the Cisco 4451-X Integrated Services Router. This flexible enhanced service module enables you to switch between T3 and E3 applications with a single Cisco IOS command.

The SM-X-1T3/E3 enhanced service module supports a single-port T3 or E3 with an integrated channel service unit (CSU) and a data service unit (DSU). It supports High-Level Data Link Control (HDLC), PPP, and Frame Relay. The SM-X-1T3/E3 includes the following features:

  • Single port—universal T3/E3 version
  • Clear and subrate support in both T3 and E3 modes
  • Online insertion and removal (OIR) support
  • Onboard processing of Cisco Message Definition Language (MDL) and performance monitoring
  • Support for scrambling and subrate can be independently or simultaneously enabled in each DSU mode
  • Support for full T3 and E3 line rates
  • Support for RFC1407–MIB

T3/E3 Applications and Positioning

The SM-X-1T3/E3 enhanced service module provides high-speed performance for advanced, fully converged networks supporting a wide array of applications and services such as security and advanced QoS for voice and video. T3/E3 and subrate T3/E3 connectivity optimizes WAN bandwidth for deploying new applications and service delivery. All supported platforms are capable of supporting full line rate performance but impose varying levels of CPU overhead and therefore affect the overall platform performance. See Table 1 for recommended branch office positioning.

Configuring the SM-1T3/E3 Service Module

The SM-1T3/E3 Service Module can be configured as a T3 interface or an E3 interface. See the following sections for configuration details:

Configuring the Card Type and Controller for a T3 Interface

When the SM-X-1T3/E3 is used for the first time, the running configuration does not show the T3/E3 controller and its associated serial interface. You can use the show version command to determine whether the router recognized the T3/E3 card and was able to initialize the card properly. After the card type is configured for the slot, the respective controller and serial interface appear in the running configuration. See Use the show version Command.

After the service module has ascertained that the card has been initialized properly, use the card type command to configure the card. If the command is accepted successfully, Cisco IOS software creates a controller and a serial interface for the card.

Perform this task to select and configure a card type and controller as T3 on 2900 and 3900 Series ISRs:

Troubleshooting Tips

You can use the methods described in this section to troubleshoot the T3/E3 service module using Cisco IOS software.

Set Loopbacks

The T3/E3 local loopback can be used to ensure that the router and the T3/E3 service module are working properly. The controller clock source should be configured to “internal.”

Use T3/E3 network loopback and remote loopback to diagnose problems with cables between the T3/E3 controller and the central switching office at the link level. For this diagnostic setup to work, if the service module is looped toward the network, the service module must be configured with the clock source as “line.”

Run Bit Error Rate Test

The service module contains onboard BERT circuitry. With this circuitry present, the software can send and detect a programmable pattern that is compliant with CCITT/ITU pseudorandom and repetitive test patterns. BERT allows you to test cables and signal problems in the field.

When a BERT is running, your system expects to receive the same pattern that it is sending. To help ensure this, two common options are available.

  • Use a loopback somewhere in the link or network.
  • Configure remote testing equipment to send the same BERT pattern at the same time.

See the bert pattern (t3/e3) command in Cisco IOS Master Commands List, All Releases for instructions on how to run BERT and check the results.

Use the show version Command

Use the show version command to determine whether the router recognized the T3/E3 card and was able to initialize the card properly. The show version command lists the hardware interfaces and controllers present in the router. You should find “1 Subrate T3/E3 port(s)” as shown in the following example.

Specifying the Interface Address on a Cisco SM-X-1T3/E3 Service Module

The Cisco SM-X-1T3/E3 features an interface port: port 0. To configure or monitor the Cisco SM-X-1T3/E3, specify the interface in the CLI. The interface address format is slot/subslot/port , where:

  • slot —Specifies the chassis slot number where the enhanced service module is installed.
  • subslot —Specifies the slot where the enhanced service module is installed.

Note Specify “0” for the subslot.


  • port —Specifies the number of the individual interface port on the enhanced service module.

Note Specify “0” for the port.


The following example shows how to specify interface 0 in the first subslot installed in chassis slot 2:

Router(config)# interface serial 2/0/0
 

This command shows a serial SPA as a representative example, however the same slot/subslot/port format is similarly used for other SPAs (such as ATM and POS) and other non-channelized SPAs.

Glossary

backplane—The physical connection between an interface processor or card and the data buses and the power distribution buses inside a chassis.

BER—Bit error rate. Ratio of received bits that contain errors.

CSU—Channel service unit. Digital interface device that connects end-user equipment to the local digital telephone loop. Often referred to together with DSU as CSU/DSU.

DS-3—Digital signal level 3. Framing specification used for sending digital signals at 44.736 Mbps on a T3 facility.

DSU—Data service unit. Device used in digital transmission that adapts the physical interface on a DTE device to a transmission facility, such as T1 or E1. The DSU also is responsible for such functions as signal timing. Often referred to together with CSU as CSU/DSU.

E3—Wide-area digital transmission scheme used predominantly in Europe that carries data at a rate of 34.368 Mbps. E3 lines can be leased for private use from common carriers.

FEAC—far-end alarm code.

Frame Relay—industry-standard, switched data link layer protocol that handles multiple virtual circuits using HDLC encapsulation between connected devices. Frame Relay is more efficient than X.25, the protocol for which it generally is considered a replacement.

HDLC—High-Level Data Link Control. Bit-oriented synchronous data link layer protocol developed by ISO. Derived from SDLC, HDLC specifies a data encapsulation method on synchronous serial links using frame characters and checksums.

MDL—Maintenance Data Link message defined in the ANSI T1.107a-1990 specification. Also, the Cisco Message Definition Language

MDL—A high-level language used to specify protocols and protocol conversion operations on the VSC.

OIR—Online insertion and removal. Feature that permits the addition, the replacement, or the removal of cards without interrupting the system power, entering console commands, or causing other software or interfaces to shut down.

PPP—Point-to-Point Protocol. Successor to SLIP that provides router-to-router and host-to-network connections over synchronous and asynchronous circuits. Whereas SLIP was designed to work with IP, PPP was designed to work with several network layer protocols, such as IP, IPX, and ARA. PPP also has built-in security mechanisms, such as CHAP and PAP. PPP relies on two protocols: LCP and NCP.

Subrate—Less than the standard rate of transmission, which is defined at the voice-grade rate of 64 kbps.

T3—Digital WAN carrier facility. T3 sends DS3-formatted data at 44.736 Mbps through the telephone switching network.

TDM—Time-division multiplexing. Technique in which information from multiple channels can be allocated bandwidth on a single wire based on preassigned time slots. Bandwidth is allocated to each channel regardless of whether the station has data to send.
