All E1 statistics data is cleared.

6.4 Performing the Diagnostic Tests

The user-controlled test functions of ASMi-52 consists of the loopback tests and

LEDs test. The purpose of these tests is to determine the source of a break in the

data flow.

• Both local and remote ASMi-52 units must be configured and synchronized

properly to allow remote loopback activation.

• Only one loopback can be activated at a time, either on the local or remote

unit.

Running Loopback Tests

ASMi-52 supports the local and remote loopbacks as per ITU V.54, by using the

following methods:

• From the supervisory terminal.

• Via corresponding pins of the synchronous interface, for the ASMi-52 with

V.35 interface and RS-530 interfaces only.

Running the Local Loopback

The local loopback (LLB) checks the performance of the local ASMi-52 modem,

the local DTE and connection between them (see Figure 6-19). The LLB can be

performed separately on the local and remote modems.

ASMi-52 allows you to set the loopback timeout causing the LLB to deactivate

automatically after the desired period of time.

Timeout set to 0 (zero) is forever. Avoid setting timeout to 0 as local control is lost

during LLB
