MLT3.0/ISDN CHANNEL TEST (TA 1500 ONLY)

Note: To traverse through the menus, select the desired entry and press Enter. To work backwards in the menu, press ESC (escape key).

8 Testing – Test functions can be activated through front panel Bantam jacks, the ADMIN port, or inband loopback sequences.

TESTING

Loopback tests – initiated from either the ISDN switch or the faceplate via the local craft interface in the Network-to-Customer direction.

Point-to-point test – initiated via the local craft interface toward either the U-interface or the T1 carrier interface.

Local Loopback – initiated from the local craft interface for either bearer channel.

Leased Mode Testing – responds to independent network-issued OCU and CSU latching loop- back sequences for B1 and B2, when configured Adjacent-to-Customer and the D channel is dis- abled.

CONNECTIONS

All connections are made through the 50-pin amphenol connector on the back panel TA 750/850/1500.

APPLICATIONS

Channel Test (LUNT Mode)

Upon detection of the Test Initiative Voltage (116Vdc behind 8kapplied to Tip with Ring open) the LUNT does the following:

The channel unit sends a Channel Test mp-eoc message downstream to the LULT, signaling the request for a MLT channel test.

The channel unit notifies the BCU/SCU that a MLT test is underway.

The unit sends a 333.3 Hz tone between the tip and ring leads. This tone is compliant with TR-TSY-OO465.

When the Test Initiative Voltage is removed, the active test status indication to the BCU/SCU is removed, a Return to Normal mp-eoc message is sent to the LULT, and the U-Interface attempts re-synchronization.

Channel Test (LULT Mode)

Upon receipt of the Channel Test mp-eoc message, the LULT does the following:

The channel unit notifies the BCU/SCU that a MLT test is underway.

The LULT connects the bypass pair. This connects the customer drop to the common equipment through TEST_R and TEST_T. The set-up sequence is complete.

Upon completion of the automatic test the bypass relay de-energizes.

The channel unit then attempts to re-synchronize the U-interface between the LULT and the NT1
