Product Review

The Cisco NM-8CE1T1-PRI module offers versatile connectivity options, supporting both T1 and E1 interfaces, which is beneficial for organizations requiring flexible network configurations for integrated voice and data applications. However, the module's operation is limited by its compatibility, specifically designed for use with Cisco 4000 Integrated Services Routers and Catalyst 8300 and 8200 Edge Series Platforms, potentially restricting its use in diverse networking environments. Moreover, while it provides a comprehensive range of features including clear-channel data, MFT packet voice, and support for unstructured E1 (G.703), the physical dimensions and environmental operating conditions dictate careful consideration of installation environments to ensure optimal performance.


The Cisco NM-8CE1T1-PRI module enhances the capabilities of Cisco 4000 Integrated Services Routers and Catalyst 8300 and 8200 Edge Series Platforms by providing eight ports for T1/E1 connectivity. This module supports clear-channel data and channelized data, allowing for flexible configuration and deployment of multiple integrated data and voice applications. With the ability to support unstructured E1 (G.703), the module caters to a wide range of networking requirements. Each of the eight ports on the NM-8CE1T1-PRI module can process serial data up to 24 per port for T1 connections and 31 per port for E1 connections, facilitating efficient data transmission. The module also supports Voice Channel Associated Signaling (VCAS), with 24 channels per port for T1 and 31 channels per port for E1, plus one channel per timeslot, enhancing its voice capabilities. Furthermore, the Primary Rate Interface (PRI) feature is available on a per-port basis, simplifying the integration of voice and data services. The NM-8CE1T1-PRI module also includes drop and insert functionality, with 24 channels per port for T1 and 31 channels per port for E1, plus one per timeslot, allowing for flexible voice and data integration. The hardware dimensions are compact, with a height of 1.25 inches, a width of 3.50 inches, and a depth of 7.24 inches, making it a space-efficient choice for networking equipment. It weighs 0.52 lbs, adding minimal weight to the installed equipment. Operating and storage temperatures for the module range from 0 °C to 50 °C and -20 °C to 65 °C, respectively, ensuring reliable performance under various environmental conditions. The module operates effectively within a relative humidity range of 10% to 85% (noncondensing) and can withstand nonoperating humidity levels from 5% to 95% (noncondensing), ensuring durability and longevity. Compliance with industry standards is key for interoperability and reliability. The NM-8CE1T1-PRI adheres to T1 compliance standards including TIA-968-A, CS-03, Jate, and ANSI T1.403. For E1, it meets TBR4, TBR12, and TBR13 standards, along with ITU-T G.703, G.704, G.823, and I.431, ensuring broad compatibility and performance consistency across various networks. Key features of the Cisco NM-8CE1T1-PRI module include: -
  • Clear-channel and channelized data support for flexible networking configurations.
  • Support for multiple integrated data and voice applications, enhancing the utility of the connected Cisco routers and switches.
  • PRI support on a per-port basis, enabling efficient setup of voice and data services.
Designed for use with specific Cisco networking equipment, the NM-8CE1T1-PRI module extends the functionality and enhances the performance of the connected devices, making it a valuable addition to businesses looking to leverage their existing network infrastructure for integrated voice and data communications.
