The Loopback Generation option specifies different loopback codes depending on the
selection of loopback generation mode above. The options for ddsT and ddsN are off (no
loopback), B1ocu (an OCU loopback on the first B-channel), B1csu (a CSU loopback on the
first B-channel), B1ds0 (a full DS0 loopback on the first B-channel), B1dsu (a DSU loopback
on the first B-channel), B2ocu (an OCU loopback on the second B-channel), B2csu (a CSU
loopback on the second B-channel), B2ds0 (a full DS0 loopback on the second B-channel),
and B2dsu (a DSU loopback on the second B-channel).
The options for v.54T, v.54N, ft1T and ft1N are off (no loopback), B1 (v.54 or Ft1 loopback
on the first B-channel), B2 (v.54 or Ft1 loopback on the second B-channel), and B1+B2 (v.54
or Ft1 loopback on both B-channels).
The options are B1 (loopback on the first B-channel), B2 (loopback on the second B-channel)
and B1+B2 (loopback on the both B-channels).
If the loopback is directed toward the DSL or U interface, the loopback pattern selected will
not start until the U-ST parameter on the test screen shows the status of actv. (See the test
section below for further information about the U-ST parameter).
RCVE
This option is not available n/a in this host release.
SEAL CURR
The Sealing Current (SEAL CURR) option is n/a for nt and lunt, off or on for lt and lult.
TR COND
The Trunk condition (TR COND) setting allows the card to pass trunk conditions from the
network to the U/ST interface when set to on. Setting the TR COND state to off prevents the
condition to be passed through the card.
