    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.

    • Cisco IOS Software configurable for T1 or E1 operation

    • Balanced or unbalanced E1 termination in the same module

    • Integrated CSU/DSU (channel service unit/data service unit) per port

    • Full or fractional E1/T1-can be fully channelized

    • Supports PRI for data, T1-CAS, and E1-CAS R2 signaling

    • E1 unframed and framed modes (G.703/G.704) available

    • Interoperates with NM-xDM digital modem network modules

    • Bantam (tty) jacks for easy network monitoring

    • V.54 loopback compatible

    • Supported on Cisco 2610-51XM, 2800, 2691, 3660, 3700 and 3800 Series routers

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

    • On-board expansion slot for future technologies

    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.
    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.
    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.
