MLT3.0/ISDN CHANNEL TEST (TA 1500 ONLY)
Channel Test (LUNT Mode)
Upon detection of the Test Initiative Voltage (116Vdc behind 8k Ω applied 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
BANTAM TEST JACKS
■ Accommodate DS0 Logic Testers such as the TPI 108/109 RT II to perform upstream and down
stream testing.

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