Figure 2-3 Slot Designation (Front View)

The PSM slots are numbered 1 through 16 (from left to right) on the bottom of the card cage. Slot 1:

Reserved for common equipment purposes (the IMC card).

Divided into two slots (A and B) for the IMC card. These slots are wired in parallel.

Provides:

Ethernet connectivity for remaining 15 slots.

BITS A and B connections for the user.

Alarm relay connections for the user.

Slots 2 through 16:

Are identical with respect to the PSM cards and Interface I/O Mid-plane.

Are wired for Ethernet connections and have point-to-point connection to slot 1.

Are coupled to both BITS A and B.

Contain alarms relay control signals for four contact closures.

The Mid-plane design:

Eliminates most of the discrete wiring within the shelf.

Provides connection between the front and back cards.

Provides the interconnection for the cards, interface I/O panels, fan tray, and -48 VDC Power Input.

Supports hot swapping of cards, Interface I/Os, and fan tray.

Has no active circuitry.

I/O Panels are installed in the rear of the chassis. Two types of I/O cards exist:

1.The PSM I/O, with two OC3 transceivers, three DS3 ports, and an RJ45 CRAFT port.

2.The IMC I/O card, with 1 Ethernet port, 1 RJ45 console port, and BITS A and BITS B ports, and a D connector for alarms.

A blank I/O panel is supplied to cover slots that do not contain one of the above cards.
