Cisco E1/T1 ISDN PRI Network Modules for Cisco 2610-51XM,
2800, 2691, 3660, 3700 and 3800 Series Routers
®
The versatility of Cisco
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.

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.
  • Page 2 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.
