The ISDN BRI port adapters provide ISDN BRI interfaces for connecting Cisco 7200 series routers to an ISDN wide-area network through an NT1 device. Each interface consists of two B channels that can transmit and receive data at the rate of 64 kbps, full-duplex, and one D channel that can transmit and receive data at the rate of 16 kbps, full-duplex.
Two models of the ISDN BRI port adapter are available:
Figure 7-52 shows the 4-port ISDN BRI port adapter, and Figure 7-53 shows the 8-port ISDN BRI port adapter.
The PA-CE3 is a next generation solution that builds on Cisco's experience with channelized DS3 and supports high density clear channel and channelized E1 connections terminated via a single E3 G.703 connection. With the flexibility to provision E1, fractional E1, and Nx64K connections the PA-CE3 reduces the management complexity of supporting large numbers of leased line connections.
The PA-CT3/4T1 for the Cisco 7200 family routers supports 28 separate T1 serial interfaces on a single DS3 interface, extending high density and cost effective T1 leased line aggregation to the 7200 platform. Functionality of the PA-CT3/41 port adapter is identical to the CT3IP-xx series channelized DS3 interface processors. The PA-CT3/4T1 meets a price/performance ratio ideal for T1 aggregation in regional ISP and enterprise data center applications.
The ATM Port Adapters are single-port (SC duplex connectors), OC-3c/STM1 (155 Mbps) ATM port adapters for the Cisco 7500 series, Cisco 7000 series, and Cisco 7200 series routers.
