The Channelized T1/E1 and ISDN PRI modules work with the digital modem module in the Cisco 2800, 2900, 3800, and 3900 Series Integrated Services Routers to provide V.90- and V.92-compliant digital dial access aggregation. The modules support balanced and unbalanced E1 connectivity and conform to the G.703 and G.704 standards for unframed and framed E1 modes. The integrated channel service unit/data service unit (CSU/DSU) function allows customers to consolidate customer premises equipment (CPE).

The modules can be used in T1E1 networks, selectable by software configuration. The different versions help enable customers to deploy different port densities according to the needs of individual offices. Three versions are available, 1- and 2-port cards in a single-wide high-speed WAN interface card (HWIC), and a 8-port cards in a single-wide network module. With flexible WAN connectivity options, together with integrated routing, security, voice, and wireless capabilities, the Cisco Integrated Services Routers can meet every need of enterprise-class branch offices today and in the future. Applications include fractionalfull T1/E1 WAN connectivity, ISDN PRI for primary WAN linkWAN backup, and dial access aggregation. The Cisco® Channelized T1/E1 and ISDN PRI High-Speed WAN Module HWIC-1CE1T1-PRI combine multiple T1/E1 WAN connectivity-Channelized T1/E1 and ISDN Primary Rate Interface (PRI), in the same card.
