T200 IDSL OFFICE CHANNEL UNIT - REMOTE (IDSL OCU-R)
INSTALLATION & TURNUP
1. Select desired options with front panel DIP switches SW1 and SW4.
2. Insert the IDSL OCU-R into its designated slot ensuring the edge connector seats firmly into the
backplane.
3. After insertion the IDSL OCU-R will run a self-test and synchronization phase during which all LEDs
undergo an On/Off sequence. Refer to Status LEDs section for descriptions.
4. After synchronization, which may take up to 50 seconds, the following LED indication will show:
■SYNC LED - Green.
■All other LEDs will be Off until network occurrences cause them to turn On.
If LEDs in step 4 are as noted, proceed with loop testing per specifications.
If LEDs in step 4 are in any other configuration, refer to Troubleshooting Guide section.
CAUTION: This product is intended for installation
in a restricted access location in a Type “B” or “E”
enclosure only.
Max input current @ max load = 32 mA @ -48 VDC
with an output of 6 mA @ 10 VDC.
WIRING CONNECTIONS
HARDWARE VERSUS SOFTWARE PROVISIONING
When SW1 and SW4 are used for option selection the options take effect when the card is inserted in the
mounting. Subsequent software provisioning will override hardware options. Depressing the LBK
pushbutton for five seconds will toggle between the two option sets.

T200 IDSL OCU-R
DUAL POWER CAPABILITY
The T200 IDSL OCU-R can be powered from either -48 VDC provided locally, or by -120 VDC from an ADTRAN
U-BR1TE-With-Power circuit card.
CONTROL PORT OPERATION
The front panel DB-9 provides an RS-232 interface for a VT100 or compatible controlling terminal. The terminal
interface operates at data rates from 1.2 to 19.2 kbps, asynchronous, 8 data bits, no parity, and one stop bit.
Terminal sessions provide access to screen menus for the following:
■Provisioning.
■Testing.
■Performance Monitoring.
Upon terminal connection, press space bar three times to access screens. Directions on the screens guide craft
personnel through the various menus.
NOTE: When conducting a Terminal Session, always select VT100 mode prior to making the craft connection.
TROUBLESHOOTING GUIDE
No Power at the IDSL OCU-R
■Check local or span power available to the IDSL OCU-R.
• Span power: Remove IDSL OCU-R. Measure T/R voltage at the T200 mounting (Tip to Ring = -118 VDC to
-122 VDC).
• If power unavailable at OCU-R, check span powering at U-BR1TE.
• U-BR1TE span power: Tip to GND = -118 to -122 VDC, Tip to Ring = -118 to -122 VDC, Ring to GND = 0.
• Local power: Check for -48 VDC across pins 17 and 35 on mounting.
■If local or span power is available a faulty IDSL OCU-R is indicated.
■If span power is required but not available, check POWER option on U-BR1TE.
Sync LED On Red
■No synchronization indicates lack of continuity between IDSL OCU-R and the ADTRAN U-BR1TE. Check
continuity of the 2-wire loop (Tip pin 41, Ring pin 47).
■Verify all deployment guidelines are adhered to.
■Relocate the IDSL OCU-R to splice points sequentially closer to the ADTRAN U-BR1TE to isolate suspect cable
sections.
Excessive Errors On Loop
■Check cable does not exceed 2 kft bridged tap.
■Ensure loop length is within deployment guidelines.
■Compare resistance of individual conductors. If different, high-resistance or intermittant opens are indicated.
A TDR is commonly used to find such faults.
Trouble Codes
The IDSL OCU-R transmits an ASC (9Eh) trouble code toward the network from the customer premises for the
following 4-wire loop faults:
■4-wire customer interface loss of signal.
■Invalid 4-wire interface framing (may be due to mismatched IDSL OCU-R and DSU/CSU data rates).
■Open loop on 4-wire customer interface.
■The ADTRAN U-BR1TE transmits an MOS (9Ah) trouble code toward the network for similar 2-wire loop faults.
■ASC (9Eh) is transmitted to the network in B1 during loopback conditions initiated by the IDSL OCU-R.
Remote Access
The IDSL OCU-R responds to or supports the following:
■ADTRAN Digital System 6 Message Protocol.
■TPI 108/109 and 105 portable test sets.
■Hekimian React 2001 Release 1.900.
■ANSI Standard T1.107-1995 “Digital Hierarchy Format Specifications Annex G.”
TESTING
For test purposes the IDSL OCU-R supports the following loopbacks and applications:
■OCU latching and non-latching loopbacks.
■Bidirectional loopback.
■Remote end initiated loopbacks from ADTRAN U-BR1TE and IDSL OCU-R.
■CSU latching and non-latching loopbacks (the IDSL OCU-R provides sealing current reversal when CSU
loopback detected).
■Loopback tests may also be initiated via the craft interface by selecting “Loopbacks”from the main menu.
LBK & Pushbutton Tests (U-BR1TE must be ADTRAN for Loopback Response from OCU-R.)
The following tests are initiated by the IDSL OCU-R LBK pushbutton:
■Press once. This loops the U-BR1TE toward the IDSL OCU-R.
■Press a second time. This loops the IDSL OCU-R toward the 4-wire customer interface.
■Pressing the LBK pushbutton a third time or while a loopback is active, disables all loopbacks.
■Depressing the LBK pushbutton for five seconds will toggle between local and remote provisioning.
Successful loopback tests initiated by the TEST/LBK pushbuttons will show the LED indications listed and will
transmit the trouble codes shown. (Applicable to D4 U-BR1TE.)
