FRONT PANEL OPTION FEATURES

FRONT PANEL LBK PUSHBUTTON SW2

Loopback pushbutton SW2 initiates loopback tests without CO or test center coordination.
Refer to LBK Pushbutton in Testing section. Depressing the LBK pushbutton for five seconds
will toggle between hardware and software option settings. The AP LED provides indication.

FRONT PANEL DIP SWITCH SW4

SC ON Enables secondary channel when 56k or below data rate is selected.
64 ON Selects 64 kbps data rate (SC must be set to OFF).
56 ON Selects 56 kbps data rate.
19.2 ON Selects 19.2 kbps data rate.
9.6 ON Selects 9.6 kbps data rate.
4.8 ON Selects 4.8 kbps data rate.
2.4 ON Selects 2.4 kbps data rate.
SW56 ON Selects switched 56 data rate (SC must be set to OFF).

FRONT PANEL DIP SWITCH SW1

-10 dB ON Selects -10 dB AMI signal across 4-wire interface to customer. (Typical installation)
OFF Selects 0 dB AMI signal across 4-wire interface to customer. (Extended demarcation
installation)
QM ON Enables Quality Monitoring. Excessive errors will cause automatic blockage of data.
OFF Quality Monitoring disabled.
EC ON Enables Error Correction, valid only at 19.2 kbps or lower.
OFF Error Correction disabled.
LLEN ON Enables response to latching loopbacks.
OFF Disables response to latching loopbacks.

FRONT PANEL DB-9 CONNECTOR

Provides an RS-232 interface for connection to a VT100 or compatible terminal or test device.

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.

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.
