More Specifications

The NM-2CT1-CSU is a network module made by Cisco that can be used in their 2600 and 3600 series routers. It provides two ports for connecting to T1 lines, which are a type of digital telephone connection that can transmit data at a rate of 1.544 Mbps. The module also includes a Channel Service Unit (CSU), which is a device that manages the physical layer of the connection and provides link-level error detection and correction.

The T1 lines can be configured for ISDN PRI (Primary Rate Interface) service, which is a digital telephone service that provides multiple "channels" for voice and data transmission. Each channel can carry a separate call, and the module supports up to 23 voice channels and one data channel on each T1 line.

This item is typically used in enterprise and service provider networks to provide multiple ISDN PRI connections to telephone systems or other network devices.

  • Innovation: It might have enhanced security features, advanced QoS capabilities, or support for new technologies such as IPv6.
