Operational Modes OCU or CSU (software selectable per line)
Loopbacks Off, DTE, Net-a, Net-d (software selectable)
(Net-a loops 4-wire interface to the network, Net-d loops to the network
at card interface to system bus)
Loopback Generation (Latching only) Various loopbacks sent in-band to remote equipment: Off, DS0-n (loops
the analog interface of the remote for 56K or less rate), CSU-N (loops
the 4-wire interface of the remote), CSU-N (loops the 4-wire interface
of local device).
Loopback Detection Off, On, On with 10 minute time-out
(Latching and Non-Latching)
