The T-1 line should be ordered as D4/SF (superframe) framing,
AMI line encoding, Robbed Bit protocol, E&M Wink start signaling.
T-1 interface DTI/SC boards can be connected directly to a channel
service unit (CSU), digital service unit (DSU) or to other network
terminating equipment. The CSU chosen must support the D4 superframe
format. Most functions traditionally performed by a DSU (such as
unipolar to bipolar format conversion, framing, etc.) are performed by
the DTI/SC board. The only exception is the ability to interpret
certain bipolar violation patterns, such as loopback start and stop
commands from the T-1 network.
Supports ISDN Primary Rate (see ISDN-PRI Support section)
Supports BoardWatch?, the SNMP-compatible software for remote CT board management.
