This section of the ADTRAN MX2820 System Manual is designed for use by network
engineers, planners, and designers who are upgrading a communications network. It contains
general information and describes system components, system connectivity, and system
modules.
SYSTEM OVERVIEW
The ADTRAN MX2820 high-density M13/STS-1 multiplexer system offers bandwidth consolidation at a low cost in a dense rackmount chassis. The MX2820 gives customers the ability to
easily install M13 or STS-1 modules on an “as needed” basis by simply inserting additional
modules.
• The MX2820 system demultiplexes a DS3 or STS-1 input signal into DSX-1 or E1 output
signals.
• The MX2820 system multiplexes DSX-1 or E1 input signals into DS3 or STS-1 output
signals.
In areas where multiple M13/STS-1 modules are needed, the MX2820 system frees up
valuable rack space with a high-density chassis. The MX2820 system with a 19-inch chassis
houses up to 14 MUX modules to provide seven redundant M13/STS-1 modules in 2U rack
units of space. The MX2820 system with a 23-inch chassis houses up to 18 MUX modules to
provide nine redundant M13/STS-1 modules in 2U rack units of space.
The MX2820 MUX modules are capable of combining independent T1s, E1s, or T1s and E1s
on the same DS3/STS-1 signal. Each pair of MUX modules provides built-in 1:1 redundancy
on the DS1 and DS3/STS-1 circuits. Advanced diagnostics include CSU loopbacks, NIU
loopbacks, Far-End Alarm Channel (FEAC) loopbacks, C-bit loopbacks, and built-in BERT (Bit
Error Rate Testing) capabilities.
As with all ADTRAN products, the MX2820 system offers comprehensive management
options. It features a VT100 terminal interface for configuration, loopbacks, and performance
monitoring. The MX2820 system has an integrated 10/100Base-T Ethernet port to support
IP-based management applications including TL1, SNMP, Telnet, and SSH.
Features and Benefits
The MX2820 high density M13/STS-1 multiplexer system provides the following features:
• Affordable DS3/STS-1 bandwidth consolidation
• Built-in 1:1 redundancy
• System Controller Unit (SCU) for centralized management
• Single IP address per shelf
• Interbank communications capability to address multiple shelves with a single IP via an
RS-485 daisy chain communication link between shelves
• Capable of backhauling multiple service types (T1/E1)
• TL1, SNMP, Telnet, and SSH management
• X.25 capability for TL1 sessions

MX2820 Shelf (19-inch or 23-inch)
This system consists of either a 19-inch wide or 23-inch wide by 3.5-inch high (2U) shelf. The
19-inch shelf can house seven redundant pairs of M13 or STS-1 MUX modules. The 23-inch
shelf can house nine redundant pairs of M13 or STS-1 MUX modules. Each M13 or STS-1 pair
provides equipment protection only. Three additional slots are available to house common
modules. One slot houses the SCU, which is used for system management. The other two slots
house redundant Clock Modules.
The shelf backplane provides connectivity between external interfaces and the SCU, and
provides connectivity between the SCU and the MUX modules.
General Features
The MX2820 shelves provide the following features:
• RJ-45 connector used as 10/100Base-T Ethernet port for Telnet, TL1, SNMP, TFTP, and
SSH
• DB-25 connector used as an RS-232 interface for synchronous X.25
• Wire-wrap posts used as an RS-485 interface for daisy chaining to multiple MX2820
shelves

The M13 MUX module acts as a multiplexer/de-multiplexer, accepting a single DS3 input
signal and provides 28 DSX-1 or 21 E1 output signals and vice-versa. The MX2820 system
allows two M13 MUX modules for each DS3 signal which provides a 1:1 redundant system.
Each M13 MUX pair communicates with each other to share provisioning information and the
presence of signals and trouble conditions. Each M13 MUX pair communicates with the
MX2820 SCU for alarm reporting and performance monitoring. Figure 1-4 shows the MX2820
M13 MUX front panel.
The MX2820 M13 MUX module provides the following features:
• Built-in 1:1 equipment redundancy
• Multiplexes 28 DSX-1 (or 21 E1 channels) into a DS3 signal
• De-multiplexes a DS3 signal into 28 DSX-1 or 21 E1 channels as allowed by DS2 framing
• Supports the M13 or C-Bit parity DS3 formats

Clock Card
• P/N 1186004L1
The MX2820 Clock Card is a plug-in card which generates a timing signal synchronized to
either of two external BITS clock references. If both BITS clock references fail, the Clock Card
will meet SONET Minimum Clock (SMC) holdover requirements to produce the clock
reference. This signal may be used by any one of the MX2820 STS-1 MUX modules to
synchronize their STS-1 transmit signals. One Clock Card is required to support the STS-1
application when an external BITS clock reference is used. Two Clock Cards provide 1:1
redundancy in the MX2820 system.
Figure 1-5. MX2820 Clock Card, –48 VDC
The MX2820 Clock Card has the following Features:
• Provides a redundant SMC source with clock holdover to any MX2820 STS-1 MUX
• Communicates to the redundant Clock Card though an asynchronous data link directly
between the two cards
• Provides another direct link to the redundant card for protection management
• Maintains full duplex link to the SCU for management, alarm notification, and card
provisioning
• Displays status using a single front panel LED
• Operates over temperature range of: 0°C to +50°C (with fans)
• Supports downloading of FLASH program data to the active and protection card
simultaneously or individually
• Meets NEBS Level 3 requirements
• Interfaces to backplane via 24-pin Future Bus connector
• Supports TL1 and SNMP in the MX2820 system

SYSTEM CONNECTIVITY
The shelf backplane contains Input/Output (I/O) connectors, control and signal routing,
power input and ground, plus the interconnections between BITS clock cards, MUX cards,
and the SCU.
Figure 1-7 shows the MX2820 Multiplexer system with management and network interfaces.
Figure 1-7. MX2820 Multiplexer System Configuration
Power Connections
The MX2820 system is designed to accommodate redundant power configurations. The
system operates with either individual supply or both supplies functioning. Dual terminals for
DC Voltage (–48 or ±24 VDC) and return are provided.
A Barrier strip connector on the shelf backplane provides the power connections for power
and the frame ground. The frame ground connection is routed to the metal MX2820 chassis.
Timing
The MX2820 system operates in local, loop (network), or external (BITS) timing mode. In the
local timing mode, an onboard timing reference is provided. In the loop timing mode, the MUX
modules synchronize with the received DS3 or STS-1 signal. Because the multiplexing/demultiplexing process is asynchronous, each DS1 channel maintains its own Transmit and
Receive timing.
External timing mode only applies to STS-1 MUX modules and requires an MX2820 Clock
module. The STS-1 MUX module synchronizes its STS-1 transmit signal to the DS1 BITS clock
signal received at the Clock module.
61186003L1-1D1-19
Page 54
MX2820 System Manual
Network Interfaces
The MX2820 system demultiplexes a DS3 or STS-1 input signal into DSX-1 or E1 output
signals.
The MX2820 system multiplexes DSX-1 or E1 input signals into DS3 or STS-1 output signals.
Each MUX module accepts a single DS3 or STS-1 input signal from the network side and
provides 28 DSX-1 or 21 E1 outputs. For 1:1 redundant system, the MX2820 system provides
two MUX modules for each DS3 or STS-1 signal.
DS3/STS-1 Interface
The MX2820 backplane accommodates each DS3/STS-1 transmit and receive signal via two
75-ohm BNC female connectors.
DSX-1 (T1/E1) Interface
The MX2820 backplane accommodates DSX-1 (T1/E1) Transmit Tip, Transmit ring, Receive
Tip, and Receive Ring signals via two FutureBus connectors, one for transmit pairs and one
for receive pairs.
Management Interfaces
Craft Port
DB-9 female connector on the SCU front panel provides an RS-232 serial VT100 interface.
Network Management
DB-25 connector on the shelf backplane provides an RS-232 interface for a synchronous X.25
connection.
RJ-45 for 10/100Base-T
RJ-45 female connector on the shelf backplane provides an Ethernet interface to allow Transmission Control Protocol/Internet Protocol (TCP/IP) communication.
RS-485
Wire-wrap posts are used as an RS-485 interface to allow daisy chaining multiple MX2820
shelves.
Alarms
Alarm Relay Contacts
Wire-wrap posts provide alarm relay contacts for Critical, Major, and Minor alarms. Each
alarm can be individually wired for Normally Open or Normally Closed.
The Critical alarm relay can be used to indicate loss of power to the shelf.
1-2061186003L1-1D
Page 55
Section 1, System Description - System Connectivity
Environmental Alarm Inputs
Wire-wrap posts provide environmental alarm inputs for ACO, AUX1, AUX2, AUX3A and
AUX3B alarms.
For ACO, AUX1, AUX2, and AUX3A, alarms are activated when the circuit between the
connecting posts is closed (a short appears across the line).
For AUX3B, an alarm is activated by a cadenced input across the input posts; this input can
be used to indicate a fan failure.

Section 2, Engineering Guidelines - Power Dissipation Considerations
Configuration Guidelines for the MX2820 System
MX2820 systems can be actively cooled with fans or passively cooled by appropriately spacing
shelves and incorporating baffles into the bay design. For maximum density, fans are recommended for the MX2820 system.
The following recommendations apply to 19-inch shelves:
• Actively cooled (multiple shelf cooling):
– Working from the bottom of the bay, install heat baffle and filter assembly (P/N
1182005L1 and 1182971L1).
– Directly above heat baffle, install up to three MX2820 Chassis (P/N 1186001L1).
– Directly above the shelves, add a heat baffle, Fan Module, and filter assembly (P/N
1182005L1, 1182006L1, and 1182971L1).
– Repeat these steps for additional shelves for up to three shelves between Fan Modules.
The filter is unnecessary on the heat baffle above the top MX2820 shelf in the rack.
– Figure 2-1 provides an example.
• Passively cooled:
– Working from the bottom of the bay, leave a 1U space between the bottom of the rack
and the first shelf. Install a MX2820 Chassis (P/N 1186001L1).
– Leave a 1U space. Install a 1U passive heat baffle (Newton P/N 0040780114).
– Leave an additional 2U space, (4U total between shelves), and install another MX2820
shelf.
– Repeat these steps to fill the bay leaving a 2U space above the top-most shelf.
– Figure 2-2 provides an example.
• Actively cooled (one-to-one pusher fan):
– Locate at least 3U space in a rack for each MX2820 chassis installation. Install a Fan
Module Assembly (P/N 1184507L1) at the bottom of the 3U space.
– Directly above the fan, install a MX2820 Chassis (P/N 1186001L1).
– Figure 2-3 provides an example.
The following recommendations apply to 23-inch shelves:
• Actively cooled (multiple shelf cooling):
– Working from the bottom of the bay, install heat baffle and filter (P/N 1181003L1 and
1181971L1).
– Directly above heat baffle, install up to three MX2820 shelves (P/N 1186001L2).
– Directly above the shelves, add a heat baffle, Fan Module, and filter (P/N 1181003L1,
1181006L1, and 1181971L1).
– Repeat these steps for additional shelves for up to three shelves between Fan Modules.
The filter is unnecessary on the heat baffle above the top MX2820 shelf in the rack.
– Figure 2-1 provides an example.

MX2820 System Manual
• Passively cooled:
– Working from the bottom of the bay, leave a 1U space between the bottom of the rack
and the first shelf, install a MX2820 shelf (P/N 1186001L2).
– Leave a 1U space, install a 1U passive heat baffle (P/N 1180002L1).
– Leave an additional 2U space, (4U total between shelves), and install another MX2820
shelf.
– Repeat these steps to fill the bay leaving a 2U space above the top-most shelf.
– Figure 2-2 provides an example.
• Actively cooled (one-to-one pusher fan)
– Locate at least 3U space in a rack for each MX2820 chassis installation. Install a Fan
Module Assembly (P/N 1186006L1) at the bottom of the 3U space.
– Directly above the fan, install a MX2820 Chassis (P/N 1186001L2).
– Figure 2-3 provides an example.

Section 2, Engineering Guidelines - Power Dissipation Considerations
MX2820 Heat Dissipation and GR-63-CORE
The following guidelines are intended to aid the designer and planner for installations of
shelves and meeting NEBS heat release objectives. Since the system supports M13 and STS1 modules, much forethought should be given to the installation and possible future
expansion. Depending on the technology employed, various scenarios and shelf densities can
be achieved. Refer to Figure 2-1and Figure 2-2 for examples of frame installations.
NOTE
An MX2820 installation that uses STS-1 modules should be
actively cooled.
Telcordia GR-63-CORE specifies the physical protection requirements and objectives for
telecommunications equipment. Often referred to as “NEBS” (Network Equipment-Building
System), these guidelines have become the de facto standard for U.S. telecommunications
equipment and include both requirements and objectives for heat dissipation.
The NEBS requirement is that the heat release of telecommunications equipment be
documented. For the system, this is done in the “Power Dissipation for an MX2820 Shelf”
section.
Shelf Level
NEBS further provides specific objectives for heat dissipation within a shelf in paragraph
O4-12 of GR-63-CORE. For an equipment shelf such as the , the relevant values are as follows
in Table 2-12 (from GR-63-CORE Table 4-6).

MX2820 System Manual
Actively Cooled
Figure 2-1 provides an example of an actively cooled bay installation that contains multiple
MX2820 shelves and also meets the NEBS heat release objectives. Based on 30-inch maintenance and 24-inch wiring aisles, 12-inch equipment depth, 5-inch rack extenders, and 26inch overall equipment width, this example allows for a NEBS heat budget of 1521 watts. Nine
23-inch MX2820 shelves are shown in the bay configuration example.
Passively Cooled
Figure 2-2 provides an example of a passively cooled bay installation that contains multiple
23-inch MX2820 shelves and meets the NEBS heat release objectives. Using the same bay
configuration as mentioned for an actively cooled bay installation, this example allows for a
NEBS heat budget of 1130 watts.
With this configuration, up to seven 23-inch MX2820 shelves could be mounted in a 7-foot
bay.
NEBS recommendations and shelf spacing guidelines should be followed for both actively and
passively cooled installations.
Pusher Fan Cooled
The Pusher fan assembly can be used when there is limited rack space (for example, adding a
MX2820 system to a rack that is already installed with other equipment). Cooling is provided
directly to the MX2820 chassis by the adjacent fan assembly.
NOTE
Higher-density applications can be achieved with rack extenders.
In the higher-density applications, as shown in the bay configura
tion examples, the rack extenders provide additional space for better cable management.
NOTE
If the MX2820 shelf is deployed in racks with other equipment, a
heat baffle should be mounted below the MX2820 shelf to provide
isolation from heat from the other equipment (with exception of the
pusher fan).

MANAGEMENT INTERFACES
Telnet, SNMP, TFTP, and SSH over 10/100Base-T
An RJ-45 connector on the backplane of an MX2820 shelf provides a 10/100Base-T Ethernet
interface for the MX2820 system. Through this interface the system connects to an Internet
Protocol (IP)/Local Area Network (LAN) host computer. Each MX2820 shelf requires one IP
address, which can be provisioned with an MX2820 menu option.
The SCU manages the Ethernet interface for the MX2820 system. The SCU controls Telnet,
SNMP, TFTP, and SSH access to each module in the MX2820 shelf.
There is one session reserved for each of the following:
•Craft
•Telnet
•X.25
•RS-485
• SSH
There are also 10 pool sessions that can connect to any of these entities.
NETWORK CONNECTIONS (DS3/STS-1)
CAUTION
DSX-1, DS3/STS-1, and 10/Base-T Ethernet circuits from the
MX2820 are not to be connected directly to outside plant facilities.
Cable Specifications
All coaxial cable for the MX2820 DS3 and STS-1 signals should meet the following minimum
specification:
• The coaxial cable should have characteristic impedance of 75 ohms.
• Nominal mutual capacitance should not exceed 20.4 pF/foot.
• The cable should conform to ANSI standard T1.102 (1993) pulse mask definition. The
standard reference cable is “WECO Type 728A” at 450 feet.
Approved cable types include:
• WECO 728A
• Lucent 728B
• Lucent 734A
• Belden 9231
• Belden 1809A
Lucent type 735A cable may be used up to a maximum length of 250 feet.
The DSX-1 (T1/E1) circuits provide connections to DSX-1 cross connects and to other
equipment based on how the circuits are to be used for an application.

Section 3
Application Guidelines
This section provides application guidelines for network designers who are incorporating a
system into their network.
The standard DS3-Fed application for the MX2820 system allows the M13 Multiplexer (MUX)
module to accept a single DS3 input signal from the network and provide twenty-eight T1 or
twenty-one E1 output signals (or a combination thereof as allowed by DS2 framing) on the
terminal (customer) side.
With a 1:1 redundant configuration, two M13 MUX modules can accept a single DS3 signal
from the network. Each M13 MUX pair communicates with each other to share information
regarding provisioning and the presence of signals and trouble conditions. Each STS-1 MUX
will communicate with the MX2820 SCU (1186003L1) with regards to alarm reporting and
performance monitoring.
One M13 MUX module, slot A in the MX2820 shelf, is considered the primary (working) unit,
and the other M13 MUX module, slot B in the MX2820 shelf, is considered the protect
(standby) unit.
DS3 Interface
The MX2820 backplane provides two standard BNC coax female connectors for the M13 MUX
module, one for the DS3 transmit path and the other for the DS3 receive path.
The 19-inch shelf provides 14 BNC connectors, and the 23-inch shelf provides 18 BNC
connectors.
DS3 Cabling Specifications
Refer to “Section 2, Engineering Guidelines” for cable specifications.
DSX-1 Interface
The MX2820 backplane provides two 60-pin FutureBus connectors for each DSX-1 signal, one
for the DSX-1/E1 transmit Tip and Ring pairs, and the other for the DSX-1/E1 Receive Tip
and Ring pairs.
DSX-1 Cabling Specifications

Section 4
Site Preparation
This section provides Site Preparation guidelines for network designers who are incorporating
an system into their network.
This section of the system manual provides details on how to prepare a Central Office (CO),
Multi-Tenant Unit (MTU), or Remote Terminal (RT) to accept the installation of one or more
MX2820 shelves. Shelves that are installed in the same bay or in adjacent bays should be
engineered together so that they share common feeds for power, timing, and management
interfaces as appropriate for the application.
PREREQUISITE PROCEDURES
Before beginning the site preparation, the Site Engineer should review the Engineering
Guidelines. Based upon the application, the Site Engineer should specify how the bay holding
the shelves should fit into the NEBS lineup for CO, MTU, or RT applications. These
considerations include which power, transmission, and clock connections are required for
each shelf.
SPACE CONSIDERATIONS
Vertical and Horizontal Space Requirements
For vertical and horitizonal space requirements, refer to the Bay Configurations figures in
“Section 2, Engineering Guidelines”.
Use of Horizontal Spaces in a NEBS Lineup
When multiple shelves are to be installed in the same bay, horizontal aisle spacers can be
used on both sides of the bay to accommodate the high-wire density of the shelves.
Fitting the Shelf into MTU and RT Applications
For individual shelf applications, the MX2820 shelf occupies 3.5 inches of rack space. Refer to
“Section 2, Engineering Guidelines” for heat baffle and fan requirements. All applications
should be implemented where there is adequate heat dissipation and available power.
4-261186003L1-1D
Page 85
Section 4, Site Preparation - Electrical Considerations
ELECTRICAL CONSIDERATIONS
The MX2820 shelf supports dual-feed –48 VDC or ±24 VDC power inputs.
Power Wiring and Fusing
MX2820 power connections, including return connections, should be provided from the fuse
panel using insulated wire and the appropriate fuse (see Table 2-7 on page 2-6). Per application requirements, power can be provided by a –48 VDC or ±24 VDC supply. A separate wire
should be run from the fuse panel for each –48 VDC or ±24 VDC input and for each VDC
return. Power wire with red insulation is recommended for the voltage feeds, and power wire
with black insulation is recommended for the return feeds.
NOTE
Applications which include STS-1 multiplexers should be –48 VDC
only.
Fan Module Power
Refer to the appropriate Installation and Maintenance Practice and/or Job Aid for Fan installation.
Frame Ground
Each MX2820 shelf requires a connection to frame ground using the appropriate AWG wire
size. See Table 2-7 on page 2-6.
FOLLOW-UP PROCEDURES
Once the Central Office preparation described in this section of the manual is complete, the
MX2820 shelves are ready for the installation. “NTP-001, Shelf and SCU Installation” provides
the instructions for installing the shelves.
