Channel Bank Replacement and Additions
In the example shown in the following diagram, the T1 access unit is a
replacement for a channel bank. The T1 access unit is more than just a
replacement for a channel bank. It can do many things that a channel bank
cannot do. A channel bank has no data ports, it passes data as if it comes from
external modems or DSUs. The T1 access unit provides both data and voice
ports. A channel bank is a “dumb” device, and therefore cannot be managed from
a remote site, while the T1 access unit can be managed via SNMP.
