ADTRAN T200 IDSL Wiring, Span Power Applications, Local Power Applications, Compliance Codes

Wiring

The ADTRAN IDSL OCU-R may be mounted in any standard T400/T200 housing, or the following ADTRAN T400/T200 housings:

CAUTION

On span-powered units, ensure ground continuity exists between the unit, the housing, and a known approved ground source.

Span Power Applications
•	Single Mount Housing	P/N 1212007L1
•	Dual Mount Housing	P/N 1212008L1

For 2-wire DDS deployment from D4/SLC-96 and SLC-5 channel banks, a repeater powering U-BR1TE is used to provide the metallic 2-wire DDS interface. In these cases, the IDSL OCU-R is span-powered with -120 Vdc and the customer premises installation should include a span-powered mounting.

Local Power Applications
• Single Mount Housing	P/N 1212007L2

For 2-wire DDS deployment from non-ADTRAN digital loop carrier U-BR1TEs, the IDSL OCU-R must be locally powered with customer provided AC. For these applications a local powered T400/T200 mounting is required.

Table 3 shows the Compliance Codes for the IDSL OCU-R. The IDSL OCU-R complies with the requirements covered under UL 1459 third edition and is intended to be installed in an enclosure with an Installation Code (IC) of “B” or “E”. The IDSL OCU-R is intended for installation in restricted access locations only. Maximum input current at max load is 32 mA @ -48 Vdc with an output of 6 mA @ 10 Vdc.

Connections are made using screwdown terminals on the barrier strip located in the rear of a single mount housing. Figure 3 describes the circuit card pinout.

Table 4 shows the wiring connections for the IDSL OCU-R.

The housing should be wired as follows:

•Network pair to terminal strip TR and TT positions.

•To Customer and From Customer pairs through customer 8-pin RJ-48 modular connector.

or

•To Customer (DRT, DRR) and From Customer (DTR, DTT ) to designated terminal strip positions.

•Local -48 Vdc power supplied to pins 17 (GND) and 35 (-48 Vdc) of mounting is provided only when the OCU-R is not span-powered from the 2-wire IDSL loop.
