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

Section 1, Introduction MX2800 STS-1 User Manual 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.

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.

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

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.

Section 1, Introduction MX2800 STS-1 User Manual 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.

10. Care should be taken not to upset the stability of the equipment rack after installation is complete.

CAUTION

Use copper conductors only for DC power and ground connection.

5. RACKMOUNT INSTALLATION

The MX2800 STS-1 can be mounted into a standard 19-inch or 23-inch equipment rack. Follow these steps to mount the unit into a rack:

1. Install the mounting flanges on each side of the MX2800 STS-1 at one of the three available positions.

CAUTION

Install the flanges only with the screws provided.

2. 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.

3. Make all network, DTE, and power connections to the rear of the unit. Refer to Power Up on page 2-2 for more information on making the DC power connection.

4. Using the 8-position modular to DB-9 female connector and the 8-position modular to 8-position modular cable, connect a VT 100 terminal device to the

CRAFT port on the front panel of the unit.

NOTE

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 internal cards. This arrangement allows the unit to operate without a cooling fan.
