DSI SS7HDC Network Interface Board -

CompactPCI Form Factor Products

DSI SS7HDC boards are high-density, high performance, multi-port, SS7 signaling

interface boards designed for use in telecommunications environments. The boards

have quad, dual, single or no signal processor(s) and support multiple HDLC-based

signaling channels, including up to 128 SS7 links that can operate at 64, 56, and 48

kbits/s. The boards are 64-bit CompactPCI boards and operate with Rear Transition

Modules (RTMs) that provide external connections. Features of the DSI SS7HDC board

are described in the following topics:

• Capacity

• Host Interface

• Physical Interfaces

• Rear Transition Modules

• Protocol Resource Support

• Visual Indicators

• Power Requirements

• Environmental Specifications

• Safety, EMC and Telecommunications Specifications

• Reliability

2.3.1 Capacity

The capacity of DSI SS7HDC boards is described as follows:

• Digital interfaces

— Eight ports for SS7HDCS8W. Eight or 16 ports for SS7HDCN16W,

SS7HDCD16W and SS7HDCQ16W with the corresponding RTM.

— T-1 or E-1 (software selectable)

— High impedance selectable

• SS7 links

— On SS7HDCQ16W boards, terminate or monitor up to 128 bidirectional

links or up to four HSL links per board

— On SS7HDCD16W boards, terminate or monitor up to 64 bidirectional

links or up to two HSL links per board

— On SS7HDCS8W boards, terminate or monitor up to 32 bidirectional links

or one HSL link per board

— On SS7HDCN16W boards, SS7 links are not supported. This board is for

use as a line interface board to provide additional T1/E1/J1 connectivity.

Note: In order to monitor both directions of a signaling link, the user must separately connect

each direction of the signaling link to the receive connection of two different LIUs on the DSI

SS7HD board.
