Page 254 SmartAX MA5612 Multi-service Access Module Maintenance Guide 8 Common Operation helping them rectify hardware faults related to off-hook and playing of dial tone, busy tone, and ringback tones. 8.7 POTS Port Loop Test There are two kinds of loop tests: hardware tests and service tests. Loop tests used to test the hardware and data configuration associated with the plain old telephone service (POTS) service.
Page 255: Performing A Loopback On An E1 Line
SmartAX MA5612 Multi-service Access Module Maintenance Guide 8 Common Operation 8.1 Performing a Loopback on an E1 Line The E1 line loopback is also called the 2M link physical loopback. When the services carried on an E1 port are abnormal, you can perform a loopback on the E1 line to check whether the E1 port is normal and whether the internal communication of the system is normal.
Page 256: Performing A Loopback On An E1 Port
SmartAX MA5612 Multi-service Access Module Maintenance Guide 8 Common Operation References The E1 line loopback is also called the 2M link physical loopback. It is a type of hardware loopbacks, namely, the loopback on a manually created hardware loop. Figure 8-1 shows the E1 line loopback.
Page 257 SmartAX MA5612 Multi-service Access Module Maintenance Guide 8 Common Operation After the port loopback is configured, the broadcast storm may occur if the E1 port is not isolated. Therefore, it is recommended that you run the undo loopback command to cancel the loopback in time after the loopback test is complete.

SmartAX MA5612 Multi-service Access Module Maintenance Guide 8 Common Operation Local loopback Remote loopback Local loopback on the E1 port Local loopback, also called inloop, is the loopback from the port processing module of the board to the backplane. In the local loopback, the signals that are transmitted from the backplane to the E1 port are directly sent back to the backplane to check whether the board that houses the E1 port can communicate with the backplane normally.
Page 259: Pots Subscriber Loop Line Test
SmartAX MA5612 Multi-service Access Module Maintenance Guide 8 Common Operation Context The user port to be tested must not be configured with any semi-permanent connection (SPC) service.
