DTM LEDs
The DTM has additional LEDs that are not on most other MBMs.
Figure 25 on page 65
shows the
location of the DTM LEDs.
Figure 25 DTM LEDs
Table 14
describes the functions of the DTM LEDs.

In service
Flashing
The T1, ETSI, or PRI trunks are out of service because a loopback test is
running or the DTM is initializing.
Loopback test
On
A continuity loopback test is running.
Receive alarm
On
A problem with the received digital transmission. This half-duplex link does
not work.
Receive error
On
A small error as a result of degraded digital transmission. Possible causes are
an ohmic connection, water ingress, or too long a loop.
Transmit alarm
On
The DTM cannot transmit. The DTM sends an alarm indication signal (AIS) to
the terminating switch. This half-duplex link does not work.
Transmit error
On
The DTM is sending a remote alarm indication (RAI) carrier failure alarm
(CFA) to the terminating switch. If the transmit alarm is not on, this error
indicates a far-end or cable problem.
All LEDS
Flashing
The DTM is initializing.
