ATMSpeed/155 MDA Switch Module
The ATMSpeed/155 MDA Switch Module (Figure 1-1) provides two slots for
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 MD A 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:
• A multimode fiber optic MDA (Model 5720-14 MDA) provides synchronou s
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) provide s
synchronous optica l 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 MD A that pro vides two separat e 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 sep arate 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.
ATMSpeed/155 MDA MCP Switch Module
The ATMSpeed/155 MDA MCP Switch Module (Figure 1-1) manages the
Centillion 50/100 switch. One (and only one) MCP module is required for each
Centillion 50/100 c hassis; howe ver, a second ATM MCP can be added for MCP
redundant capability.
The ATMSpeed/155 MD A MCP module has both a serial por t (Mini DIN 8) and a
10BASE-T port (RJ-45) to connect a network management station.

module has two sl ots f or ins talling MD As tha t pro vi des ATM port connec ti vity f or
different media types. A fully equipped MDA MCP switch module therefore has
four ports for making ATM connections. You can install differe nt MDAs in one
MDA MCP switc h module a s needed t o obtain m aximum fle xi bility of conne ction
types.
The MDA M CP switch module provides different types of ATM connectivity
through the following MDAs:
• A multimode fiber optic MDA (Model 5720-14 MDA) provides synchronou s
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) provide s
synchronous optica l 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 MD A that provides two separat e 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.

Using the Centillion 50/100 ATMSpeed/155 Switch Modules and Media Dependent Adapters
Caution:
Centillion 50/100 modules use electronic components that are
sensiti ve to stati c elect ricity. Static dischar ge fr om your clothi ng or other it ems
around you, even at levels that do not create a spa rk, can cause damage.
You should take all possible prec autions to prevent static discharge damage
when working with printed circuit boards. Keep each board in its protective
conductive bag until you are ready to install it. Before you touch a printed
circuit board, be sure to put on a grounded antistatic wrist strap and leash to
free yourself of static.
If you lack a grounded antista tic wrist strap and mat, be careful to stand in one
place where you work ( so you do not generate st atic electric ity by f ric tion) and
to free yourself of static by touching the metal of a grounded chassis before
handling a printed circuit board.
Installing the ATMSpeed/155 Module
You can insert or remov e an ATMSpeed/155 module from a chassis while the
power is on without interrupting service in the other modules. This ability is
referred to as “hot-swapping.”
2-2
Note:
ATMSpeed/155 modules can be hot inserted in a chassis at any time.
Howe ver, before removing an active module from the Centillion 50/100
chassis, either unplug all port cables or disable all ports on the module. This
step deactivates the module. For additional infor mation, see “
Removing a
Module” and “Replacing a Module” later in this c hapter.
To install and secure the module in the c hassis, follow these steps:

Parameter Descriptions
The physical type, networks timing, physic al media type and speed of the ATM
ports are not configurable. They are fixed at the fa ctory for each model type. You
can use SpeedView to enable or disab le the s ta te of an AT M por t.
The loop timing, networ ks timing, scrambling, and physic al loop parameters are
configurable, as described in this section.
Loop Timing
When loop timing is disabled, the local clock generates transmit tim ing. When
loop timing is enabled, timing is derived from the receive side of the port.
Network Timing
When network timing is enabled, the clock is derived from an input port and can
be distributed to any of the output ports on a module (it may not be distr ibuted to
other modules across the backplane).
Scrambling
SONET uses a scrambling algorithm to prev ent long strin gs of zeros or ones from
being transmitted. Most ATM equipment has sc rambling enabled. Although you
can disable scrambling, the destination port must also have scrambling disabled.
Predefined Configurations
SpeedView does not offer predefined configurations for ATM. Configuration
instructions appear in Using SpeedView 3.0 for Windows.
