OPTI-6100 Installation and Turn-Up Practice

Clock Considerations

If an external (BITS) clock input is required, wire run(s) from the clock source to the bay must
be provided. Use a 22 AWG or 24 AWG shielded 2-wire cable with drain for this run. Use one
run each for the primary and secondary clock.

MDF Considerations

Most central office applications of the OPTI-6100 require the chassis to be connected to the
Main Distribution Frame (MDF) to provide loop-side cross-connects to customer loops. The
exact wiring requirements for MDF connections are determined by the specific system appli-
cation of each chassis. RT and MDU/MTU applications require similar wiring for cable runs.

Wiring Connections to the MDF

To connect the chassis to a standard MDF Terminal Block, use 24 AWG, 28-pair twisted,
shielded transmission cables with 64-pin female connectors on the chassis end. The number of
cables required is determined by the system application.
Cables designed for this application can be ordered from ADTRAN. These cables have the shield
connected to pin 64 of the connector. Since the OPTI-6100 chassis provides a ground
connection on pin 64 of each pair connector, simply plugging these cables into the chassis
provides proper grounding of the cable shield.

Horizontal-Side Terminal Blocks

A separate terminal block location on the side of the MDF should be reserved for each chassis
to be installed. At installation, the terminal block for each chassis should be mounted on the
MDF. The other end of the cable should be routed to the anticipated location of the chassis and
labeled to indicate the terminal block location and which connector is attached at the other end
(A, B, C, etc.).
