Introduction
1. PRODUCT OVERVIEW
The MX2800 STS-1 is a SONET multiplexer that consolidates T1 and E1 signals into an STS-1 signal.
This unit provides a cost-effective, versatile tool for combining independent T1s or E1s over the same
STS-1 carrier.
Embedded SNMP (simple network management protocol) and Telnet are available through the modem
port using SLIP/PPP or through the 10Base-T ethernet port. Using the Management Information Base II
(MIB II), RFC 1595 standards, and an ADTRAN enterprise MIB, the MX2800 STS-1 can be configured,
monitored, and diagnosed with standard SNMP network management programs such as HP OpenView™
(from Hewlett Packard) and Spectrum
remote monitoring, collecting, and logging of MX2800 STS-1 events in real time. This information can be
useful during installation setups and/or troubleshooting.
Complete configuration, loopbacks, and performance monitoring are available through SNMP, Telnet, or a
VT100 terminal interface. This connection can be made via ethernet, a local EIA-232 link, or through the
built-in V.34 modem. The modem can dial-out a “cry for help” for units located in unmanned facilities.
The MX2800 STS-1 is designed for either desktop use or for installation in a 19-inch or 23-inch rack.

(from Cabletron). In addition, the SysLog Host Daemon allows
The major features of the MX2800 STS-1 are as follows:
• Built-in 1:1 redundancy
• Hot-swappable controller cards
• Independent, dual-load sharing, redundant power supplies
• Embedded SNMP and Telnet management through 10Base-T ethernet or SLIP/PPP dialup
• Detailed performance monitoring for local and remote units
• Simplified configuration through the VT100 terminal menu structure
• Integrated V.34 modem for dial-up and dial-out access
• Capable of backhauling multiple service types (T1/E1)
•AC or DC power
• VT Hairpinning
• VT cross-connect to any DS1
• NEBS Level 3 compliant

STS-1 Overview
Controller Card 1:1 Redundancy
The MX2800 STS-1 supports two hot-swappable controller cards which provide 1:1 redundancy for the T1
and STS-1 signals as well as the STS-1 connections. With two cards installed, the MX2800 STS-1 can
recover from circuit or network failure, depending on the configuration. Refer to Section 7, Circuit Redun-
dancy for more information.
2. STS-1 OVERVIEW
The MX2800 STS-1 multiplexer delivers up to 28 T1s or 21 E1s via the SONET Synchronous Transport
Signal Level One (STS-1) at a speed of 51.84 Mbps. This is a cost-effective method for providing T1/E1
signals without the need for costly and complex multi-level multiplexing/demultiplexing as in an M13
multiplexer. The T1/E1 signals can be directly multip lexed into the SONET STS-1 signal, allowing simplified add and drop functionality.
The MX2800 STS-1 multiplexer also implements VT hairpinning and VT cross-connect mapping. Any VT
can be hairpinned back to the STS-1 signal for dropping further down the SONET ring. Cross-connect
mapping permits a VT to be mapped to any of the 28 available physical ports. The relat ionship of MX2800
STS-1 components and SONET terminology is illustrated in Figure 1-1.

STS-1 Framing Structure
The STS-1 frame is organized as 9 rows by 90 columns of bytes. See Table 1-1. This frame is transmitted
row by row, from left to right, and with the most significant bit (MSB) of each byte transmitted first. It is
defined to operate at the basic rate of 8 kHz or 125 microseconds per frame, or 8,000 frames per second at
a bit rate of 51.84 Mbps.
The frame is divided into two parts to physically segregate the layers:
• Transport Overhead
• Synchronous Payload Envelope
The first 3 columns make up the transport overhead (TOH); the remainder is the synchronous payload
envelope (SPE). The TOH has 3 rows for the section overhead (SOH) and 6 rows for the line overhead
(LOH). The SPE has one column for the path overhead (POH). The remaining 86 columns are for payload
data (49.536 Mbps).

Transport Overhead (TOH)
The first three columns are the TOH, which contains the overhead bytes for the Section and Line layers.
Section overhead is comprised of 9 bytes and Line overhead is comprised of 18 bytes.
STS-1 Synchronous Payload Envelope (SPE)
The SPE has 87 columns and 9 rows of bytes for a total of 783 bytes. Column 1 contains the STS Path
Overhead and has 9 bytes. The remaining 774 bytes are available for payload.
61204659L1-1A 1-3
Section 1, Introduction MX2800 STS-1 User Manual
STS-1 Overview
Virtual Tributaries (VT)
The SPE is divided into seven virtual tributary groups, made up of 12 columns each. Smaller tributaries are
multiplexed together to form these groups. For example, there can be four VT1.5 tributaries in a VT group
or three VT2 tributaries. A VT1.5 tributary consists of three columns per STS-1 frame and has a bit rate of
1.728 Mbps, allowing transport of a T1 at 1.544 Mbps plus required overhead. A VT2 uses four columns
per STS-1 frame and has a bit rate of 2.304 Mbps, allowing transport of an E1 at 2.048 Mbps plus required
overhead.
STS-1 Pointers
There are several mechanisms that allow for timing compensation between the STS-1 and its low-speed
tributaries. The MX2800 STS-1 multiplexer uses pointer adjustments to achieve timing compensation.
Pointer adjustments allow the synchronous payload envelope (SPE) to float with respect to the SONET
frame. The pointer is contained in the H1 and H2 bytes of the path overhead (POH), and is a count of the
number of bytes that the J1 byte is away from the H3 byte, not including the transport overhead. When
timing differences exist, dummy bytes are inserted into the SPE without affecting data. The receiving end
can recover the payload since the pointer is adjusted to indicate where the payload overhead (POH) starts.
Unit Timing
The MX2800 STS-1 multiplexer allows four timing methods:
• Loop Mode
• Free-Running Mode
• External Nonrevertive Mode
• External Revertive Mode
Loop Mode
The multiplexer derives timing from the incoming STS-1 signal.
A failure in this signal, such as a loss-of-signal (LOS) or a loss-of-framing (LOF) will cause the unit to
enter Holdover (HO) mode for the duration of the receive signal defect. During HO, the unit will continue
transmitting at the same rate as the receive signal prior to entering its defect condition. Stability of the
transmit during HO is guaranteed to ± 4.9 ppm over 24 hours. The defect condition must be cleared before
LOOP time mode can be resumed.
Free-Running (FR) Mode
In this mode, an internal oscillator is used to generate transmit timing.
SONET minimum clock specification of ± 20 ppm.
FREE-RUNNING mode provides a
External Nonrevertive and Revertive Modes
EXTERNAL timing mode allows the MX2800 STS-1 to derive its transmit timing from the BITS clocks
through wire-wrap pins located on the back of the chassis. Two sources can be specified to provide external timing: a primary and a secondary source. Failure of the primary source (due to LOS or AIS) will cause
1-4 61204659L1-1A
MX2800 STS-1 User Manual Introduction, Section 1
SNMP
the unit to switch to the secondary source, if available. When in External Nonrevertive timing mode, the
timing source will not switch back to the Primary External Clock in the event that it becomes available. If
in External Revertive timing mode, the timing source will switch back to the Primary External Clock if it
becomes available. In the event that both the primary and secondary sources are lost, the unit will enter
Holdover mode as described previously . Holdover mode will be exited upon recovery of at least one clock
source.
3. SNMP
The embedded SNMP feature of the MX2800 STS-1 allows the unit to be accessed and controlled by a
network manager through the 10Base-T local area network (LAN) port. The MX2800 STS-1 supports the
MIB-II standard, RFC 1213, RFC 1595, and the ADTRAN Enterprise Specific MIB.
NOTE
MIB files are available from ADTRAN in the support section of the
ADTRAN Website at www.adtran.com.
The term SNMP broadly refers to the message protocols used to exchange information between the
network management system (NMS) and the managed devices, as well as to the structure of device
management databases. SNMP has three basic components:
•Network manager
•Agent
•MIB
Network Manager
The network manager is a set of control programs that collect, control, and present data pertinent to the
operation of the network devices. These programs reside on a network management station.
Agent
The agent is a control program that resides in every network device. This program responds to queries and
commands from the network manager, returns requested information or invokes configuration changes
initiated by the manager, and sends unsolicited traps to the manager.
MIB
A MIB is an industry standard presentation of all status and configuration parameters supported by a
network device.

Telnet
4. TELNET
Telnet provides a password-protected, remote login facility to the MX2800 STS-1 that allows a remote
user to control the MX2800 STS-1 through the terminal menus. Only one Telnet menu session may be
active at a time.
5. TL1
Transaction Language 1 (TL1) is an ASCII based language that supports both command-response and
autonomous (NE) message generation. Commonly, TL1 is used over a X.25 packet network but is
completely independent of any physical layer protocols. For the MX2800 STS-1, TL1 is implemented as a
Telnet session running over either Ethernet or PPP. Up to eight TL1 Telnet connections may be active at a
time.
6. AVAI LABLE OPTIONS
The following optional equipment is available for use with the MX2800 STS-1. Contact a local distributor
or the ADTRAN sales department for more information.
Breakout Panel (P/N 1200291L1)
The optional breakout panel connects to the MX2800 STS-1 and provides 28 RJ connectors for the individual T1s/E1s. Shipment includes two six-foot, 64-pin to 64-pin amphenol cables which allow direct cabling
to the MX2800 STS-1 (refer to Connecting the Breakout Panel on page 2-5 for more information).
BNC Patch Panel (P/N 1200291L5)
The optional BNC Patch Panel connects to an MX2800 Chassis or equivalent and is mountable to a
19-inch rack. The panel converts the T1/E1 transmit-and-receive signal interfaces from 120-ohm amphenol interfaces to 75-ohm coaxial (BNC). This allows easy 75-ohm impedance-matched access to both the
transmit and receive lines of each T1/E1 channel. Each of the twenty eight BNC interfaces is configurable
as either balanced or unbalanced. The frame ground of the patch panel is connected to a ground lug accessible on the rear of the patch panel. See Figure 1-2.

Select Network Interface to access the network configuration parameters (Figure 3-5). Configure the
MX2800 STS-1 network settings appropriately for the application.
Figure 3-5. Network Configuration Menu
Menu-option descriptions are described in the following sections:
• STS-1 Configuration on page 3-5
• Protection Co nfiguration on page 3-7
• Miscellaneous on page 3-8
• External Clock Configuration on page 3-8
STS-1 Configuration
Use the STS-1 Configuration selections described below to configure the STS-1 network settings to match
an application.
Line Length
Set the line length to reflect the physical length of the STS-1 network line, as follows:
• Set the line length to
• set it to
Short if the distance is less than 225 feet
Long if the cabling distance is between 225-450 feet
Timing
This option determines the source of timing used to derive the transmit signal. The MX2800 STS-1 has
four modes of timing operation:
61204659L1-1A 3-5
Section 3, Configuration MX2800 STS-1 User Manual
Network Interface
•Loop
• Free-Run
• External Nonrevertive
• External Revertive
Loop
Loop timing configures the unit to recover timing from the STS-1 receive signal. Loss of the STS-1 receive
signal or reception of AIS causes the unit to enter hold-over mode (refer to Loop Mode on page 1-4 for
information on hold-over mode). The STS-1 receive signal must be valid for at least 10 seconds for the unit
to exit hold-over mode and restore loop timing.
Free-Run
When the unit is configured for Free-Run timing mode, timing is derived from a +/–20 ppm internal reference providing a SONET Minimum Clock (SMC).
External Nonrevertive
Setting the unit to External Nonrevertive or External Revertive timing mode configures the unit to derive
timing from one of the two external sources selected in the Primary External Clock (
ary External Clock
(Sec Ext) options. These are external BITS clocks that may be terminated on the two
PRI Ext) and Second-
sets of wire-wrap pins on the back of the MX2800 chassis. The external clock source may be disabled (if
only one source exists, or no external clock sources are desired). When both sources are configured, failure
of one source causes the unit to switch to the other source (if it is a valid source).
When in External Nonrevertive timing mode, the timing source does not switch back to the Primary external clock in the event that it becomes available.
External Revertive
When in External Revertive timing mode, the timing source switches back to Primary External clock if it
becomes available.
Failure of both sources causes the unit to enter hold-over mode. At least one external clock source must be
valid for at least 10 seconds for the unit to exit hold-over mode and restore external clock timing.
XCV Threshold
The XCV Threshold (excessive code violations threshold) sets a limit on code violations accepted by the
unit before it switches controller cards. If set to Disabled, code violations do not cause the unit to switch
controller cards. The threshold limits are described in the following chart:
Setting The unit switches controller cards if...
-3
1E

Network Interface
VT Mode
The seven VT groups may be configured to carry either VT1.5 or VT2 tributaries.
• When set for VT1.5 (T1), all VT groups are set for VT1.5[TU=11] at 1.728 Mbps and the ports are set
for T1 at 1.544 Mbps.
• When set for VT2 (E1), all the VT groups are set for VT2[TU=12] at 2.304 Mbps and the ports are set
for E1 at 2.048 Mbps. When set for VT2, the last 7 VTs (VT 22-28), and the last 7 ports (ports 22-28)
become unavailable.
Protection Configuration
The MX2800 STS-1 houses two controller cards for 1:1 protection against hardware failu re. The two cards
can also provide network protection, supporting two STS-1 circuits simultaneously. The menu selections
allow customization of setup parameters.
Active Controller
This field displays
controller cards to switch. For example, if controller card
A or B, indicating the active controller card. This setting can be used to force the
A is active and B is selected, a switch-over
occurs immediately.
Network Protection
This option allows enabling or disabling of the ability to automatically route the STS-1 to the backup facility in the event of a facility failure.
• Network Protection =
Enabled: All information is automatically routed to the backup facility in the
event of a primary facility failure.
• Network Protection =
Disabled: The primary STS-1 facility (A) is utilized at all times.
NOTE
When choosing a setting for Network Protection, cabling and network
provisioning issues must be considered. For configuration examples of
the different modes of protection, refer to Section 7, Circuit Redundancy.
Max. (Maximum) Switch Threshold
The value entered in this field determines the number of times per hour the unit is allowed to switch
between controller cards. If protection switching occurs more than the Max. Switch Threshold within one
hour, the unit issues a trap and inhibits automatic protection switching for the next 24 hours. The default
setting is 3 times an hour. This count may be cleared by clearing protection switch alarm counts (refer to
Protection Switch Statistics on page 5-13).

System management is possible through either SNMP, TL1, or VT-100 menus. Access is possible via craft
port, SLIP/PPP modem port, or 10Base-T ethernet interface. The menu (Figure 3-10) includes options to
customize alarm and trap generation, security setup, and equipment identification. The availability of some
options in this menu vary depending upon the configuration of other options.

CAUTION
Configuration changes to Local IP Address, Gateway IP Address, Subnet
Mask, Management Port, Modem Mode, Modem Baud Rate, and IP Hosts
will not be implemented unless all Telnet sessions are closed. Changes
made while a Telnet menu session is active will invoke a warning
message on the console.
NOTE
If the unit is not equipped with an internal modem, the Management Port
option and Dialup Options will not be available.
Management Options
Local IP Address
This option is utilized to enter the MX2800 STS-1 IP address. This IP address applies to the LAN or
modem port (when configured for PPP or SLIP). This address is available from the network administrator.
Gateway IP Address
If the MX2800 STS-1 and the network manager are connected through a gateway node, a gateway IP
address for the MX2800 STS-1 is required in this field. If an IP packet is to be sent to a different network,
the unit sends it to the gateway.
Subnet Mask
This option is utilized to enter the subnet mask of the MX2800 STS-1. This address is available from the
network administrator.
Management Port
This option is utilized to assign the management port as either LAN or Modem. The Modem setting applies
only to units equipped with an internal modem.
Dialup Options
This option is utilized to configure the dialup capabilities of the MX2800 (see Figure 3-1 1). These options
apply only to units equipped with an internal modem.

System Management
Figure 3-11. Dialup Options Menu
Primary and Secondary Phone Numbers
When the MX2800 dials out to send a trap, it first dials the Primary Phone Number. If the call is unsuccessful, it tries the Secondary Phone Number. Attempts between the two numbers continue until a call is established and the trap is reported (or until each number’s maximum redial attempts is reached; refer to
Maximum Redial Attempts below).
Initializing String
This AT command in this field is used to initialize the modem, and is normally left at the default setting of
ATZ.
Dial String
This AT command causes the modem to dial out, and is normally left at the default setting (ATDT).
Maximum Redial Attempts
This setting controls the number of times a call is attempted. If a successful call is not established after the
final attempt, the MX2800 discards the trap messages.
Idle Timeout
After establishing a call and sending trap messages, the MX2800 remains online for the number of seconds
set in this field. If the field is set to 0, the unit disconnects as soon as the trap is sent.
Connection Timeout
This setting determines the number of seconds the MX2800 waits for a connection. T iming begins as soon
as the dial command is issued. This field must be set for greater than 20 seconds.

MX2800 STS-1 User Manual Configuration, Section 3
System Management
Pause Between Calls
This is the delay, in seconds, that the MX2800 waits between redial attempts.
Dialout On Trap
Enable or disable the MX2800’s ability to dial out to report traps.
Answer on Ring
Enable or disable the ability to accept incoming calls. If enabled, incoming calls are automatically
answered by the MX2800. This enables performance of remote management functions via modem dialup.
Modem Mode
Select the Modem port function for the application (VT-100, PPP, or SLIP). The Modem port, located on
the rear panel of the MX2800, provides a telephone line (POTS) for connection to the internal V.34
modem. This setting applies only if the Management Port option is set to Modem.
When configured for
VT-100, the MX2800 reports error conditions in plain ASCII with the following
information:
• The Unit ID value programmed in the Equipment Identification portion of the System Management
screen (refer to System Management on page 3-16)
• A trap code indicating the error condition
• A text description of the fault
• The date and time when the error was logged
When configured for
PPP or SLIP, the MX2800 logs into the PPP/SLIP host and reports the error condi-
tions to the hosts designated under Trap IP Addresses (refer to Trap IP Addresses on page 3-21).
Modem Baud Rate
Set the maximum operating speed of the Modem port (1200, 2400, 4800, 9600, 19200, and 38400 bps).
The default setting is 38400 bps.
Hangup
Selecting this option forces the MX2800 to end an established call.
Last Modem Response
This status field displays the last modem response to the MX2800 as one of the following:
• OK
• Connect
•Busy
• Error
• No Dialtone
