Introduction
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 costeffective , ver sat il e t ool for combining independent T1s or E1s ove r
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 10BaseT 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 Hewlett Packard’s HP OpenView™
and Cabletron’ s Spe ctrum™. In addi tion, the SysL og Host Daemon
allows 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, diagnostics, and performance monitoring
are available through SNMP, Telnet, or a VT-100 terminal
interface. This connection can be made via ethernet, a local EIA232 link, or through the built-in V.34 modem (see the note at the
end of this section on page 1-2). The modem can di al-ou t 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.

which provide 1:1 red undancy f or the T1 and STS-1 signal s as wel l
as the STS-1 connections. With two cards installed, the MX2800
STS-1 can recover from circuit or network failure, depending on
the configuration. See Chapter 7, Circuit and Networ k Redundancy
for more information.

STS-1 OVERVIEW
The MX2800 STS-1 multiplexer del ivers 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 way to provide T1/E1
signals without the need for costly and complex multi-level
multiplexin g/demultiplexing as in an M13 multiplexer. The T1/E1
signals can be directly multiplexed into the SONET STS-1 signal,
allowing simplified add and drop functionality.
The MX2800 STS-1 multiplexer also implements VT hairpining
and VT cross-connect mapping. Any VT can be hai rp inn ed bac k to
the STS-1 signal for dropping further down the SONET ring.
Cross-connect mapping per mits a VT to be mapped to any of the 28
available physical ports.
STS-1 Framing
The STS-1 frame is organized as 9 rows by 90 columns of bytes.
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.
Chapter 1. Introduction
The frame is divided into two parts to physically segregate the
layers. 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 s ect io n over hea d (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).
STS-1 Pointers
There are several mechan isms 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
61200659L1-1 MX2800 STS-1 User Manual 1-3
Chapter 1. Introduction
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 line overhead
(LOH), and is a count of the number of bytes 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 adjus ted t o indi cate where t he pay load o ver head
(POH) starts.
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.
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 exa mple, th ere can be f our VT1.5 tri butaries
in a VT group or three VT2 tributaries. A VT1.5 tributary consists
of three column s per STS-1 frame and has a bit r at e of 1.728 Mbps,
allowing transport of a T1 at 1.544 Mbps plus requir ed ove rhead. A
VT2 uses four columns per STS-1 fr ame and has a bi t rat e of 2.304
Mbps, allowing transport of an E1 at 2.048 Mbps plus required
overhead.

Unit Timing
Chapter 1. Introduction
The MX2800 STS-1 multiplexer allows three timing methods. The
OOP
first is
L
timed, in which the multiplexer derives timing from
the incomin g STS-1 signal. A failure in this signal, such as a lossof-signal (LOS) or a loss-of-framing (LOF) will cause the unit to
OLDOVER
H
enter
defect. During
(HO)
mode for the duration of the receive signal

, the unit wi ll continue tr ansmitting at the same
rate as the receive signal prior to entering its defect condition.
Stability of the transmit du ring
over 24 hours. The defect condition must be cleared before
HO
is guaranteed to +/- 4.9 ppm

OOP
time mode can be resumed.
The second mode of operation is
F
(FR)
mode. In this
REE-RUNNING
mode, an internal oscillator is used to generate transmit timing.
REE-RUNNING
F
mode provides a SONET minimum clock
specification of +/- 20 ppm.
The third timing operation mode is
XTERNAL
E
XTERNAL
E
.
timing
mode allows the MX2800 STS-1 to derive its transmit timing from
any one of the 28 DSX-1/E1 physical ports. Th e ports s elect ed may
be data carrying ports. 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 the unit to swi tch to
the secondary s ource, i f availabl e. In t he event that both the primary
OLDOVER
and secondary sources are lost, the unit will enter
H
mode
as described previously. Holdover mode will be exited upon
recovery of at least one clock source.
SNMP
The MX2800 STS-1's embedded SNMP feature allows the unit to
be accessed and controlled by a network manager through the
10BaseT local area network (LAN) port. The MX2800 STS-1
61200659L1-1 MX2800 STS-1 User Manual 1-5
Chapter 1. Introduction
supports the MIB-II standard, RFC 1213, RFC 1595, and the
ADTRAN Enterprise Specific MIB.
MIB files are available 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,
the network manager, the agent, and the 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 c ontrol p rogram tha t resi des in ev ery ne twork devi ce.
This program responds to quer ie s an d commands fr om the netwo rk
manager, returns requested information or invokes configuration
changes initiated by the manager, and sends unso li ci te d tr aps to the
manager.
MIB
A MIB is an industry standard presentation of all status and
configuration parameters supported by a network device.
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 te rminal men us. Only one Telnet session may be
active at a time.

TL1
Chapter 1. Introduction
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. Only one TL1 Telnet
connection can be active at a time.

RACKMOUNT INSTALLATION
The MX2800 STS-1 can be mounted into a standard 19-inch or
23-inch equipment rack. Follow these steps to mount your unit into
a rack:
1. Prepare the MX2800 STS-1 mounting ears by scraping the
paint away from the mounting ears’ portion that makes contact
with the rack and the portion where the screw mounts into the
side of the MX2800 STS-1.
2. Install the mounting flanges on each side of the MX2800 STS- 1
at one of the three available positions.
Be sure to install the flanges with the screws provided.
3. After the flanges have been installed, position the MX2800
STS-1 at the correct location within the rack and secure the
mounting flanges to the mounting rails of the rack.
Chapter 2. Installation and Operation
4. Make all network, DTE, and power connections to the rear of
the unit. See Power Up on page 2-2 for more information on
making the DC power connection.
5. Using the 8-position modular to DB- 9 female connec tor and th e
8-position modular to 8-position modular cable, connect a
VT 100 terminal device to t he
CRAFT
port on the front panel of
the unit.
Two MX2800 STS-1s may be stacked with no spacing between units.
ADTRAN recommends 1U (1.75") of separation above and below the
two stacked units. This spacing allows the unit to dissipate heat. The
design of the MX2800 STS-1 uses the chassis to distribute heat
generated by the unit's internal cards. This design allows the unit to
operate without a cooling fan, which increases its overall reliability.

The controller card is receiving a line alarm
indication signal. The Section Terminating
Equipment generates AIS-L after detecting LOS
or LOF.
AIS-P (Path Alarm Indication Signal)
The controller card is receiving a path alarm
indication signal. AIS-P is defined as all ones in
bytes H1, H2, and H3 as well as all ones in the
entire STS synchronous payload envelope.
RFI-L (Line Remote Failure Indication)
The controller card is receiving a line remote
failure indication. RFI-L is declared when the
incoming line remote defect indication (RDI-L,
“110” pattern in bits 6, 7, and 8 of the K2 line
overhead byte) lasts for 2.5 +/- 0.5 seconds.

RFI-P (Path Remote Failure Indication)
The controller card is receivinga path remote
failure indication. RFI-P is declared when the
incoming path remote defect indication (RDI-P, “1”
in bit 5 of the G1 path overhead byte for
contiguous frames) lasts for 2.5 +/- 0.5 seconds.
SLM-P (Path Signal Lavel Mismatch)
The controller card is detecting a signal label
mismatch. A received signal label is mismatched
if it does not equal the locally provisioned value or
the value “equipped non-specific”.
UEQ-P (Path Unequipped)
The controller card detects that the path is
unequipped. The path is unequipped if it is not
provisioned. Byte C2 of the STS path overhead is
set to zero.
