Router Hardware Features
Figure 1-1, Figure 1-2, Figure 1-3, and Figure 1-4 shows the rear panels of the
Cisco 2520/CPA2520, Cisco 2521/CPA2521, Cisco 2522/CPA2522, and Cisco
2523/CPA2523 routers, respectively.
The multiport serial routers function not only as multiprotocol routers but also as
communication servers (see Figure 1-1) for telecommuting services. The multiport serial
routers offer high-speed synchronous serial lines for T1 connections, and low-speed
asynchronous/synchronous serial lines to attach terminal equipment such as a channel
service unit/data service unit (CSU/DSU).
Figure 1-1 through Figure 1-4 show the rear panels of the multiport serial routers.
