Results
The DSU does not generate the test results.
NOTE
When a DSU (control or tributary)
originates Remote Digital
Loopback, both the originating
DSU and the receiving DSU are in
Test mode: the originating DSU is
in RL and the targeted DSU is in
DL. No other test can be run at
the originating or receiving DSUs
until Remote Digital Loopback is
aborted.

Bilateral Loopback

Bilateral Loopback is a combination of DTE and
Digital Loopbacks operating simultaneously in the same
DSU, which is shown in Figure 4-8. Bilateral Loopback
(Bilat Lpbk) or Digital Loopback is a customer-selectable
configuration choice from the General (Gen)
configuration option set in Chapter
NOTE
If the Bilat Lpbk (Bilateral
Loopback) configuration option is
enabled, requesting a Remote
Digital Loopback or Digital Test on
a port automatically initiates a
DTE Loopback on the port, as
well. Requesting an aggregate
Remote Digital Loopback or
Digital Loopback automatically
initiates a DTE Loopback on all of
the ports.
