DS3 I/O Card - EXS-DS3-1100/EXS-DS3-1100R
Description
The DS3 I/O card recovers clock and data from the incoming DS3 signal, and facilitates line protection for the DS3 line card. It also supports the DS3 Standby I/O card to deliver N+1 redundancy.
Placement
The DS3 I/O card resides in the rear card slots of a CSP 2090, CSP 2110 or CSP 2040 chassis. The DS3 Standby I/O card must reside in a slot numbered one greater than the Primary DS3 I/O card. For example if the Primary DS3 I/O card is in slot six, the standby DS3 I/O card must be in slot seven.
Two DS3 cable assemblies are supplied with the DS3 I/O card to support redundancy. See the DS3 Cable Assembly, Hardware Product Description.
Always use the supplied DS3 cable assemblies when connecting the DS3 I/O card and a DS3 Standby I/O card for redundancy or when connecting a DS3 I/O card directly to the network. Using other cables may damage the connectors on the DS3 I/O and Standby I/O cards and cause a failure or intermittent operation.
When interfacing the DS3 I/O and Standby I/O cards with any electrical equipment with the DS3 cable assembly, proper wiring and grounding procedures must be followed. If not, ground loops may result which are dangerous and can result in physical harm as well as possible signal interference. See Chapter 4, Card Installation in the CSP Installation and Maintenance Guide.
The part number, serial number, model number, and revision are located on the back of the PC board.
