Rev 1.00
Index Indicator Front Panel Description
1 POWER This green LED lights whenever power is applied to the 1544E unit.
2 BPV/CRC
/FBE
This red LED lights (0.1 seconds minimum) for each occurrence of Bipolar Violations (BPV),
Cyclic Redundancy Check errors (CRC), or Frame Bit Errors (FBE).
3 AIS This red LED lights if an unframed all ones signal is detected from the network or DTE.
4 LOS This red LED flashes with Loss Of Signal from the network or the DTE.
It lights constantly if an Out Of Frame (OOF) condition is detected.
5 YELLOW This red LED lights if a yellow alarm (far end receiver out of sync) is detected from the network or the DTE.
6 DENSITY This red LED lights if the ones density of the received data from the DTE is less than 12.5%.
7 LINE LOOP This yellow LED lights if the unit is in a line loop condition.
8 TEST LOOP This yellow LED lights if the unit is in a local or remote test loop. It flashes if the DC loop pair is activated.
9 SET/RESET This yellow LED flashes if a set or reset code is being transmitted. It lights if a test is in progress.
10 NET FAULT This red LED flashes in conjunction with Indicators 2, 3, 4, and 5 to show that the detected fault or error is coming from
the network. It lights if a CPU fault has occurred or a fault condition exists on the network.
11 DTE FAULT This red LED flashes in conjunction with Indicators 2, 3, 4, and 5 to show that the fault or error is coming from the DTE.
12 Test Jacks These bantam jacks provide access to the T1 line on the DTE side. Refer to the detail on this page.
13 TEST This is a 3-position rocker switch used for performing a network test or a local loopback. See description below.
14 T-View port Provides direct terminal access for controlling the CSU and gathering status and facility performance data.
15 Brackets Use the 2 holes on each bracket to bolt the 1544E to the rack mount kit or wall.

TOP: The NET jack access ports break connection to the DTE and
make connection to the CSU in the direction of the network.
MIDDLE: The MON ports are used for monitoring the signals
passing through the CSU (between the DTE and the network).
BOTTOM: The DTE ports break connection to the CSU and make
connection to the DTE.

TEST
NET (network test): When depressed, the CSU
loop code is transmitted for 5 seconds.
NRM (normal operation): When moved from
NET back to NRM, the CSU sends a loop down
code. When moved from LOC back to NRM, the
local loop back is removed.
LOC (local loopback): When depressed, the CSU
performs a local, bidirectional loop.
