General Description

The TA 850 BCU is a common module plug-in unit de- signed for the TA 850. The BCU, with a built-in CSU, provides all control functions for the TA 850 common units and all individual access modules. A faceplate ADMIN DB-9 provides access for a VT100 terminal for screen menu provisioning, and bantam test jacks pro- vide transmit and receive monitoring. An additional TEST DB-9 provides timing for DS0 test equipment. A network LED shows status information for the network T1. The unit comprises a main circuit board and daugh- ter card and inserts directly into the BCU slot on the TA 850 shelf. An 8-position DIP switch is mounted on the daughter card and is used for T1 provisioning and clocking.

Functional Description

The TA 850 BCU provisions, operates, monitors, and tests all TA 850 access modules including Quad FXS, Quad FXO, OCU DP, DS0 DP, and Nx56/64 DSU DP.
