Cisco SM-X-1T3/E3 Overview

  • 1Description

The Cisco SM-X-1T3/E3 1-Port Clear-Channel Packet-over-T3/E3 Service Module for Cisco Integrated Services Routers allows you to switch between T3 and E3 applications with a single Cisco IOS software command. This feature offers you increased flexibility and investment protection by allowing a Cisco partner, service provider, or enterprise customer to stock only a single product that can be deployed internationally.

The module provides an integrated line interface unit (LIU) DSU that allows T3 or E3 lines to be directly terminated on a Cisco router, eliminating the need for external DSU equipment, simplifying the T3/E3 line management, reducing provisioning cost, and freeing valuable rack space. It supports the proprietary subrate and scrambling features of T3 DSU vendors such as Digital Link, Larscom, and ADC Kentrox. Subrate support in the module maximizes the utility of these products in service provider environments. By simultaneously supporting interoperability with a wide range of third-party DSU vendors, this module offers the flexibility to support installed equipment without locking customers into a proprietary solution.

The Cisco T3/E3 Service Module provides direct connectivity to a T3 line for full-duplex communications at the T3 rate of 44.736 MHz and full-duplex E3 communications at 34.368 MHz. It provides the performance requirements to deploy advanced voice, video, and data applications over the WAN and supports key Cisco IOS Software features and services such as quality of service (QoS), Network-Based Application Recognition (NBAR), IP Security (IPsec), Firewall, intrusion detection system (IDS), Network Address Translation (NAT), and NetFlow. The service module supported in all Cisco IOS software feature sets, and does not require additional memory.

Module Features
  • One-port T3 with DSU or E3 with DSU module
  • T3/E3-specific features for monitoring, bit error rate tester (BERT), MIBs, alarms, and more
  • Ability to independently or simultaneously enable scrambling and subrate in each DSU mode
  • Supported DSU Vendors' Algorithms: Digital Link, Kentrox, Larscom, Verilink, and Adtran
  • Supported Serial Encapsulation Protocols: Frame Relay, Point-to-Point Protocol (PPP), and High-Level Data Link Control (HDLC)
  • 16-bit cyclic redundancy check (CRC
Management Features
  • Line and payload loopback capabilities
  • DS-3 remote-line loopback (through Far-End Alarm and Control [FEAC] codes per ANSI T1.107a)
  • Response to embedded loopback commands
  • Insertion of loopback commands into transmitted signal
  • Programmable pseudorandom pattern up to 32 bits long, including 223, 220, 215, 1s, 0s, and alt-0-1
  • 32-bit error count and bit-count registers
  • Alarm detection-alarm indication signal (AIS), remote alarm, far-end block error (FEBE), and out of frame (OOF)
  • Onboard processor for Maintenance Data Link (MDL)
  • Combination of T3 and E3 options in a single module
  • Physical Space Savings: Eliminates the need for external DSU device, saving valuable rack space
  • Simplified Management: Eliminates the need for two separate monitoring tools
  • Software-Configurable T3/E3: Provides the flexibility to deploy a single module worldwide
