Data Sheet

The versatility of Cisco® 2610-51XM, 2800, 2691, 3660, 3700 and 3800 series routers is demonstrated by their broad support of E1/T1 connectivity and Integrated Services Digital Network Primary Rate Interfaces (ISDN PRI). Customers continue to deploy E1 and T1 circuits for Wide Area Network (WAN) connectivity, ISDN dial-backup, and digital modem termination in the Power Branch Office Environment. Cisco now makes it possible to terminate T1 and E1 PRI connections in a single network module. Available in single and dual port models, the NM-1CE1T1-PRI and NM-2CE1T1-PRI cards coupled with Cisco 2610-51XM, 2800, 2691, 3660, 3700 and 3800 Series routers, enhance and simplify customers' WAN connectivity options (Figure 1).

Figure 1. Single-Port E1/T1 ISDN PRI Network Module (NM-1CE1T1-PRI)

The Cisco E1/T1 ISDN PRI Network Module's integrated channel service unit (CSU) provides direct connection to the Telecommunications network, thus allowing customers to consolidate customer premises equipment (CPE). This provides multifunction dial access aggregation, routing functionality, VPN and firewall security, and other capabilities right inside the Cisco router in power branch office environments. Both the 1-port and 2-port versions offer support for balanced and unbalanced E1 connectivity and conform easily to customers' specific applications.
The Cisco E1/T1 ISDN PRI network modules also supply connectivity for internal digital modems in the Cisco 3660, 3700 and 3800 series routers, with connectivity options for PRI, T1 channel associated signaling (T1-CAS), and E1-CAS R2 signaling. This provides for a high concentration of V.92-compatible modems, while still allowing expandability for other critical services.

FEATURES AT-A-GLANCE

• Online insertion and removal (OIR) supported on Cisco 3660 3745 and 3845 routers

• On-board expansion slot for future technologies

KEY BENEFITS

Enhanced Flexibility

The Cisco E1/T1 ISDN PRI network modules (NM-xCE1T1-PRI) are software configurable between E1 or T1 operation, balanced or unbalanced E1 termination, and CSU/DSU. Customers no longer need to buy a specific module for T1 support and then another card for E1 connectivity. In addition, the same modules provide for balanced (120-ohm) and unbalanced (75-ohm) E1 termination. See table 5 for available cable adaptors.

Support for G.703 Unstructured E1 Signaling

International Telecommunications Union (ITU) signaling standard G.703 was previously available only on Cisco midrange routers through the VWIC-xFT-G703 Voice/WAN interface card, which did not support data PRI. Framed E1 (G.704) is also supported for international customers without G.703 service.

High-Density PRI Connectivity Options

For midrange, high-density ISDN PRI applications, the Cisco 2610-51XM, 2800, 2691, 3660, 3700 and 3800 Series provide superior performance and port density. For example, a fully configured Cisco 3745 system can be configured for up to eight ISDN PRI connections in one chassis. These ports can be fully channelized to provide up to 192 T1 channels at 56/64 Kbps each, or 240 E1 channels at 56/64 Kbps each.

Increased Manageability and Troubleshooting

Critical loopback support makes the 1-port and 2-port Cisco E1/T1 ISDN PRI network modules easy to manage. Both models have the capability to internally loop back the on-board framer chip towards the interface, thus eliminating the need for an external loopback plug. Local, remote, line, and payload loopbacks, along with support for V.54 inline loop commands complement the Cisco E1/T1 ISDN PRI Network Modules' management features.
Integrated bantam (tty) jacks allow line monitoring equipment to be inserted for circuit troubleshooting. The single set of jacks can be software selected to monitor port-0 or port-1 without interrupting service.
Blue, yellow, and red alarm detection, as well as a new command to disable yellow alarm detection and generation, gives customers better control over their WAN connections. This feature, combined with support for the Cisco WAN Access Performance Management System (WAPMS), Cisco Intelligence Engine 2100, and CiscoWorks makes troubleshooting easy when necessary

Reliability

Integrating the external E1/T1 terminating device (CSU/DSU) increases the overall system reliability. Possible points of failure are reduced by eliminating the second power supply, additional fans, extra cabling, and other equipment that accompany a "two-box" solution. This increase in reliability allows Service Providers to more easily and cost effectively meet the requirements of their customers' Service Level Agreements (SLAs) and provides enterprises with maximum equipment uptime.

PLATFORM SUPPORT

Supported Platforms and Minimum Software and Memory Requirements

Memory requirements depend on the selected platform, software feature set, and other installed modules and features. The Cisco E1/T1 ISDN PRI network modules are supported in the Cisco 2610-51XM, 2800, 2691, 3660, 3700, and 3800 routers. For information about memory planning, refer to the software release notes, the Cisco IOS Software Upgrade Planner, or ask your local Cisco representative.
