ATMSpeed/155 MDA Switch Module

The ATMSpeed/155 MDA Switch Module
installing MDAs to provide ATM port connections. Each MDA provides one of
the following: two fiber cable OC-3c ports, two STS-3c UTP ports, two coaxial
DS3 ports, or two coaxial E3 ports; a fully equipped MDA switch module
therefore has four ports for making ATM connections. You can install different
MDAs in one MDA host module as needed to obtain maximum flexibility of
connection types.
The MDA switch module provides different types of ATM connectivity through
the following MDAs:
•
•
•
•
•

ATMSpeed/155 MDA MCP Switch Module

The ATMSpeed/155 MDA MCP Switch Module
Centillion 50/100 switch. One (and only one) MCP module is required for each
Centillion 50/100 chassis; however, a second ATM MCP can be added for MCP
redundant capability.
The ATMSpeed/155 MDA MCP module has both a serial port (Mini DIN 8) and a
10BASE-T port (RJ-45) to connect a network management station.

Overview of the ATMSpeed/155 Modules and Media Dependent Adapters
A multimode fiber optic MDA (Model 5720-14 MDA) provides synchronous
optical network/synchronous digital hierarchy (SONET OC-3c/SDH
STM-10) connectivity over 62.5/125 µm multimode fiber cable.
An unshielded twisted pair (UTP) MDA (Model 5720-15 MDA) provides
STS-3c/STM-1 connectivity over Category 5 UTP cable.
A single-mode fiber optic MDA (Model 5720-17 MDA) provides
synchronous optical network/synchronous digital hierarchy
(SONET OC-3c/SDH STM-10) connectivity over 8.5/125 µm single-mode
fiber cable.
The Model 5720-31 MDA is a DS3 MDA that provides two separate channels
with two 75-ohm BNC coaxial connections for each channel. The DS3 level
signal provides B3ZS encoding with a bit rate of 44.736 Mb/s +/- 20 ppm.
The Model 5720-41 MDA is a E3 MDA that provides two separate channels
with two 75-ohm BNC coaxial connections for each channel. The E3 level
signal provides HDB3 encoding with a bit rate of 34.368 Mb/s +/- 20 ppm.
