It supports both T1 and E1 digital interfaces, allowing each port to be independently configured for voice or WAN services. Ideal for enterprise branch offices and service provider environments, this module enables channelized and unchannelized connections, offering support for data, voice, and signaling applications such as PRI and CAS. When combined with a DSP module (e.g., PVDM4), it transforms Cisco routers into powerful voice gateways for PSTN connectivity and unified communications solutions. Key Features: Interface Type: 2-port T1/E1 multiflex trunk (MFT) Compatibility: Cisco 4000 Series ISRs (e.g., 4321, 4331, 4351, 4431, 4451) Configuration Mode: Each port independently configurable as T1 or E1 Channelized Support: Yes (up to 24 channels for T1, 31 for E1) Voice Gateway Support: Requires DSP module (PVDM4) for voice services Protocols Supported: HDLC, PPP, Frame Relay, PRI, CAS, QSIG Data Services: TDM-based WAN access and inter-office connectivity Form Factor: Network Interface Module (NIM) Hot-Swappable: When router is powered down Use Cases: Voice and WAN integration in branch or hybrid network environments This module is ideal for organizations requiring high-density digital voice and data connectivity over T1/E1 lines, with flexible configuration and seamless integration into Cisco ISR-based branch or enterprise networks.
