Description The Cisco NM-1T3/E3 is a single-port network module that provides T3/E3 WAN connectivity for Cisco 2600, 3600, and 3700 series routers. Designed for high-speed broadband access, it supports both internal and external clocking options with a maximum data rate of 44.736 Mbps (T3) or 34.368 Mbps (E3). Technical Specifications Condition New/Never Used Surplus Brand Cisco Category Networking Modules Part Number NM-1T3/E3 Subcatecory WAN Interface Cards Interface Type T3/E3 Data Rate T3: 44.736 Mbps / E3: 34.368 Mbps Connector Type BNC Clocking Options Internal (450 ft), External (655 ft) Encapsulation Supported Frame Relay, ATM, Transparent HDLC Installation Type Plug-and-Play (Internal Module) Operating Temperature Range 32°F to 104°F (0°C to 40°C) Humidity Range 10% to 85% non-condensing Power Requirements 5V DC, 1.8A Dimensions (H x W x D) 1.75 x 7.3 x 7.5 inches Weight 1 kg Information About NM-1T3/E3 The NM-1T3/E3 is an internal plug-and-play module offering full-duplex communication over a BNC interface and supports encapsulation methods such as Frame Relay, ATM, and HDLC. It operates within a temperature range of 0°C to 40°C and supports both PPP and HDLC protocols for versatile WAN deployment. With Bit Interleaved Parity (BIP) error correction and support for internal and external clocking, it ensures data integrity over short- to medium-range distances. Key Features: Dual T3/E3 Support: provides flexible high-speed WAN connectivity up to 44.736 Mbps (T3) or 34.368 Mbps (E3). Wide Compatibility: designed for Cisco 2600, 3600, and 3700 series modular routers. Encapsulation Options: supports Frame Relay, ATM, Transparent HDLC, and PPP protocols. Clocking Flexibility: operates with both internal and external clocking (450–655 ft range). Error Correction: includes Bit Interleaved Parity (BIP) for improved data integrity. Plug-and-Play Installation: installs easily as an internal module for simplified deployment. The NM-1T3/E3 enables high-speed WAN connectivity with robust protocol support and flexible clocking in modular Cisco routing platforms.
