Dialogic® DS3 I/O Card - EXS-DS3-1100/EXS-DS3-1100R

Description

The Dialogic® 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 Standby DS3 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 Standby DS3 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.

Important! The DS3 I/O card supports line length of 0-225 feet.

Additional Equipment

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 Standby DS3 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.

Grounding

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.

Configuration Information

The part number, serial number, model number, and revision are located on the back of the PC board.

Notation that describes line card redundancy, where N is the number of installed line cards of a single card type and 1 is an additional line card of that type designated as a standby card. For example, if you have three T-ONE cards and one additional standby T-ONE card installed, the system provides redundancy by activating the standby card if any of the three active T-ONE cards fail.
