DPC Loopback Test
DPC LOOPBACK TEST
This test is the intra-office loopback test on the DPC card using a modem tester. There are two
kinds of loopback (Loopback 1, Loopback 2) as shown in Figure 4-1. Either the Loopback 1 or
the Loopback 2 can be selected by switch settings on the DPC card.

DPC Loopback 1 Test
(1) Set the SW1 on the DPC card as shown below.
(2) Confirm whether the LB01 lamp (for No. 0 circuit) or the LB11 lamp (for No. 1 circuit) on the 
DPC card lights.
 If the LB01 lamp or the LB11 lamp does not light, check the switch settings on the DPC card 
and the system data assignment.
(3) Connect a modem tester to the DPC card as shown in Figure 4-2.

(4) Set the attributes of modem tester (transmission rate, etc.).
(5) To confirm whether the data is transmitted correctly, send the PN Pattern 9 (511 Pattern) 
from the modem tester.
(6) Count bit errors on the modem tester for 1 minute.
 If bit errors do not occur, the cable connection between DPC card and modem tester is 
normal.
