ADTRAN 850 specifications Options, Electronic Provisioning

The TA 850 BCU plugs directly into the controller slot in the common module area of the TA 850 chassis. To insert, hold the unit by the faceplate while supporting the bottom side. Align the card edges to the guide grooves for the designated slot. Insert into the chassis until the edge connector seats firmly into the backplane. Lock the unit in place by pushing in on the locking le- ver.

CAUTION

This product is intended for installation in Re- stricted Access Locations only and is intended to be installed in equipment with a Type "B" or "E" in- stallation code.

3. OPTIONS

The TA 850 BCU can be provisioned from either an 8-po- sition Dual In-line Package (DIP) switch (S1) mounted on the PCB, or through screen menus accessed via the face- plate craft interface port. Basic T1 provisioning, clock source, and CSU loopback options are found on the DIP switch. Refer to Table 3 on page 4 for DIP switch S1 pro- visioning information. Additional and more in-depth provisioning options for the BCU as well as access mod- ules are available through the craft ADMIN interface.

DIP switch S1 must be provisioned while the BCU is withdrawn from the chassis. Once installed, any soft- ware provisioning made will override the DIP switch settings. If the unit is withdrawn and reinserted (power cycled), the software options remain in effect. If a DIP switch setting is changed while withdrawn, the new DIP switch setting takes effect. If none of the DIP switch settings were changed, the unit will be provisioned for the last software settings.

Electronic Provisioning

The ADMIN interface on the TA 850 BCU is used to change factory selected options and obtain access mod- ule status through menu screens. To access the menu screens, connect a VT 100 terminal or computer running a terminal emulation program to the craft interface port using a standard male-to-male RS-232 DB-9 cable. Craft port settings are as follows:

•9600 Baud

•No parity

•8 Data bits

•1 Stop bit

CAUTION

The BCU retains provisioning setup when re- moved from the chassis. If inserted into another chassis, the provisioning setup is invoked on that chassis' access modules.

Windows Hyperterminal. Windows Hyperterminal can be used as a VT 100 terminal emulation program. Open Hyperterminal by selecting PROGRAMS / AC- CESSORIES / HYPERTERMINAL. Refer to the Help section of Hyperterminal for additional questions.

NOTE

To ensure proper display background in Windows Hyperterminal, select VT 100 terminal emulation under SETTINGS.

Password. When connected, enter the password. The factory default is PASSWORD in all capital letters. The password can be changed to a user selected password once connected.

Menu Navigation. To traverse through the menus, se- lect the desired entry and press Enter. To work back- wards in the menu, press the Esc (escape) key.

Time Slot Assignment (Plug and Play Environ- ment). The TA 850 can support a plug and play envi- ronment for slots 1-6 of the TA 850 bank for the various access modules (i.e., FXS, FXO, OCU DP, DSO DP, UBRITE, E&M, etc.). Each card that is plugged in to slots 1-6 will consecutively take 4 Time Slots automati- cally when installed in the TA 850 bank, depending on the card that is plugged into the shelf.

Time Slot Assignment - Software Assignment (Non-Plug and Play Environment). Slots 1-6 of the TA 850 Bank are for the various access modules supported by the the TA 850 (i.e., FXS, FXO, OCU DP, DSO DP, UBRITE, E&M, etc.). The T1 interface on the TA 850 BCU supports 24 Time Slot Assignment which can be allocated to the access modules, to the DSX-1, or to the Nx64 module. The TA 850 BCU can override the plug and play assignments through the software menus via the ADMIN port on the TA 850 BCU.
