Line loopbacks for TE type NPCs provisioned on MXR/EMXR circuit packs
(KCR1s/KCR5s), even though provisioned within a Hybrid DS3U, are not
supported.
An E1 or DS1 line loopback on an HDS3U will be activated without regard to
whether a DS3 loopback is already active. If a DS3 line loopback is active (see
command I.26161), the DS1 or E1 line loopback will have no effect until the DS3
line loopback is removed.
If a DS3 equipment loopback is active, the DS1 or E1 (LOCN NEND) line
loopback will be operating, but it results in a circular transmission path for the DS1
or E1, which is most likely undesirable.
If a loopback is active another loopback request to the same NPC will be denied.
Local and far-end loopbacks are dropped during a system reset or a system
reboot.
