Chapter 1 Introduction PRODUCT OVERVIEW The MX2800 is an M13 multiplexer that consolidates T1 and E1 signals into a T3 circuit. This unit provides a cost-effective, versatile tool for combining independent T1s, E1s, or a combination of the two over the same T3 circuit. The MX2800 houses two hot-swappable controller cards which provide 1:1 redundancy for the T1 and T3 signals as well as the T3 connections.
Chapter 1. Introduction The major features of the MX2800 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 10BaseT ethernet or SLIP/PPP dialup • Detailed performance monitoring for local and remote units • Simplified configuration through the VT 100 terminal menu structure • Integrated V.
Chapter 1. Introduction T3 OVERVIEW A T3 provides the same bandwidth as 28 T1s. Typically, leasing a T3 line costs the same as eight to ten T1s. Using the MX2800, a single T3 can provide internet connectivity and voice (local and long distance) to individual sites across up to 28 individual DSX-1s. T3 is also extremely cost effective for backhauling local and long distance voice.
Chapter 1. Introduction 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 that allows a remote user to control the MX2800 through the terminal menus. Only one Telnet session may be active at a time. AVAILABLE OPTIONS The following options are available for use with the MX2800.

Chapter 3 Configuration To configure the MX2800, use a 10BaseT ethernet connection, a SLIP/PPP modem port, or a VT 100 terminal. Figure 3-1 shows the main configuration terminal menu, and Figure 3-2 shows the CONFIGURATION menu tree. Figure 3-1.
Chapter 3.
Chapter 3. Configuration NETWORK INTERFACE Select NETWORK INTERFACE to access the network configuration parameters (see Figure 3-3). Configure the MX2800 network settings to match the DS3 signal received from the service provider. Figure 3-3. Network Configuration Menu DS3 Configuration Use the DS3 CONFIGURATION selections to configure the DS3 network settings to match your application.
Chapter 3. Configuration Timing In most cases, configure the MX2800 for LOOP timing to derive timing from the network. However, set to LOCAL if the MX2800 is the master timing source for the circuit, or set to EXTERNAL 44.736 MHZ if timing is derived from an external device that is connected to the EXT CLK port. Remote Loopbacks Enabling this option allows the MX2800 to respond to remote loopback requests received over the DS3 Far End Alarm and Control (FEAC) channel when operating in C-bit parity mode.
Chapter 3. Configuration Protection Configuration The MX2800 houses two controller cards for 1:1 protection against hardware failure. The two cards can also provide network protection, supporting two T3 circuits simultaneously. The selections in this menu allow you to customize the unit’s protection setup: Active Controller This field displays A or B, indicating the active controller card. This setting can be used to force the controller cards to switch.
Chapter 3. Configuration Miscellaneous Loopback Timeout Sets the loopback timeout to DISABLED, 1 MIN., 5 MIN., 10 MIN., 15 MIN., 30 MIN., 45 MIN. or 1 HR. DS2 Configuration The MX2800 can individually frame each of the seven DS2 streams in M12 (four T1s) or G.747 (three E1s) format. When set to M12 (4XT1), the four T1s for the selected group are framed per ANSI T1.107. When set to G.747 (3XE1), the first three T1/E1 ports of the selected group are framed per CCITT G.747 into the DS3 stream.
Chapter 3. Configuration A DS2 can be divided into either three E1s or four T1s. Therefore, when dealing with an E1 configuration, some of the fields in the T1/E1 INTERFACE menus do not apply (and therefore display N/A). T1/E1State Set unused T1/E1 lines to DISABLED. Set used lines to ENABLED (see Figure 3-5). Figure 3-5. T1/E1 State Menu Set Multiple Use SET MULTIPLE (see Figure 3-6) to enable or disable any or all of the T1/E1s at one time.
Chapter 3. Configuration Figure 3-6. Set Multiple Menu T1/E1 Line Coding Set the line code for each individual T1/E1 interface to match the connected device (see Figure 3-7). The choices available for T1 are AMI and B8ZS. The choices available for E1 are AMI and HDB3. Select SET MULTIPLE to set any or all of the T1s (or E1s) to the same value at the same time. See Set Multiple on page 3-7 for a description of the SET MULTIPLE selection, entering the line code for each line. Figure 3-7.
Chapter 3. Configuration T1/E1 Line Length Set the line length for each T1 interface according to the distance from the MX2800 to your DTE device (see Figure 3-8). Set to -7.5 dB if the attached DTE device only supports DS1 levels. The E1 LINE LENGTH is not selectable and remains at 0-3000 FT. Select SET MULTIPLE to configure the line length for any or all of the T1s to the same length at the same time.
Chapter 3. Configuration Figure 3-9. Loopback Detection Menu T1/E1 Circuit Protection Choose which T1/E1 lines to protect (see Figure 3-10). If a T1/E1 is set to DISABLED, then the failure of that one line will not cause the controller cards to switch. If set to ENABLED, then the line’s failure could cause the cards to switch (depending on the PROTECTION THRESHOLD setting in this menu). The PROTECTION THRESHOLD setting determines how many of the ENABLED lines must fail before a card switch occurs.
Chapter 3. Configuration Figure 3-10. Circuit Protection Menu T1/E1 Line Identification Enter user-configurable text strings to name the individual T1/E1 lines (see Figure 3-11). You can enter up to 18 alpha-numeric characters in this field, including spaces and special characters (such as an underbar). Figure 3-11.
Chapter 3. Configuration XCV Threshold Set a limit on code violations (CVs) accepted by the unit over an individual T1/E1 line before it switches controller cards. If set to DISABLED, code violations will not cause the unit to switch controller cards. The threshold limits are described in the following chart: Setting The unit switches controller cards if... 1E-3 more than one out of every 1,000 bits received on a T1/E1 line contains a code violation.

Statistics T1/E1 Statistics The MX2800 keeps track of LOSS OF SIGNAL ALARMS, BIPOLAR VIOLATION COUNTS, AIS LOOP ALARMS, and AIS CARRIER ALARMS for each of the T1s and E1s (see Figure 5-12). View this information in one of the three time period selections, or view a cumulative alarm count. Information in these fields is for the given time period (if any) since the last reset. Figure 5-12.
Chapter 6 Diagnostics The DIAGNOSTICS menu allows you to initiate loopback tests from the MX2800. Figure 6-1 shows the main DIAGNOSTICS menu. From this menu select T1/E1, DS3, or DS2 LOOPBACKS. Once this selection is made, a second menu appears displaying the types of tests available. Descriptions and testing diagrams of the loopback tests are provided in the following portions of this chapter: T1/E1 Loopbacks on page 6-2 DS3 Loopbacks on page 6-7 DS2 Loopbacks on page 6-9 Figure 6-1.
Chapter 6. Diagnostics T1/E1 LOOPBACKS After you select the number that corresponds with the line you want to test, the menu in Figure 6-2 appears. The sections following the figure provide descriptions and illustrations of the testing options. Select 1-DATA MODE to end a test in progress. Figure 6-2.

Chapter 6. Diagnostics CSU Loopback A CSU LOOPBACK enables the MX2800 to generate a CSU loop-up pattern (001001…) towards the T1 CSU attached to the selected T1 line for six seconds. After six seconds have elapsed, the pattern will cease and incoming network traffic will be passed through to the CSU device. If the CSU device responded to the CSU loop-up pattern, it will return all data back towards the network. A loopdown pattern (0000100001….

Chapter 6. Diagnostics Figure 6-12. DS2 Diagnostics Menu DS2 Network A DS2 NETWORK loopback test loops the selected DS2 back to the network (DS3) prior to being passed through the M12/G.747 demultiplexer. All T1/E1s attached to that DS2 will receive data normally, but all data inserted into the T1/E1s attached to the selected DS2 will be ignored and replaced by the incoming DS2 network data. This test is illustrated in Figure 6-13.
Chapter 7 Circuit and Network Redundancy The MX2800 provides backup measures of protection for both circuit and network failure. The following sections describe the three possible modes of operation: • Non-Redundant Mode, which offers no backup protection, is described on page 7-2. • Circuit Failure Recovery Mode, which offers backup protection in the event of controller card failure, is described on page 7-3.
Chapter 7. Circuit and Network Redundancy NON-REDUNDANT MODE In Non-Redundant Mode, the MX2800 houses only one controller card and only one network connection is available. There is no failure protection. In the event of a failure, an alarm is initiated and the front panel LEDs reflect the condition. See Figure 7-1 for an illustration. Figure 7-1. Non-Redundant Mode In this mode, the DS3 must be connected to the IN and OUT jacks for DS3 A.
Chapter 7. Circuit and Network Redundancy CIRCUIT FAILURE RECOVERY MODE In Circuit Failure Recovery Mode, two controller cards are installed and a single DS3 line is coming in (see Figure 7-2). In this mode, the MX2800 can continue operating in the event of a controller card failure. When both cards are healthy, the primary card actively processes data while the secondary card stands by ready to take over if the first fails.
Chapter 7. Circuit and Network Redundancy Table 7-1. Configuration Requirements for Circuit Recovery Selection Path Recommended Setting Config > Network Interface > XCV Threshold 1E-3 (see the following note) Config > Network Interface > Network Protection Disabled Config > Network Interface > Max. Switch Threshold 3 Config > Network Interface > Min.
Chapter 7. Circuit and Network Redundancy CIRCUIT AND NETWORK FAILURE RECOVERY MODE In this mode, two controller cards are installed and connected to two individual DS3 lines. This is, of course, the most complete mode of redundancy. In this mode, the primary controller card is connected to the primary DS3 line and the secondary controller card is connected to the secondary DS3 line.
Chapter 7.
Chapter 8 Power Loss Recovery The MX2800 provides backup measures of protection for both power supply and power source failure. The following sections describe the possible modes of operation: 61200290L1-1 • Non-Redundant Power Mode, which offers no backup protection, is described on page 8-2. • Power Supply Recovery Mode, which offers backup protection in the event of power supply card failure, is described on page 8-3.
Chapter 8. Power Loss Recovery NON-REDUNDANT POWER MODE In Non-Redundant Power Mode, the MX2800 houses only one power supply card and only one power source is available. There is no power failure protection. If a power supply card fails, then the unit is down until the card is repaired or replaced. See Figure 8-1 for an illustration. MX2800 Figure 8-1. Non-Redundant Power Mode Power supplies are hot-swappable.
Chapter 8. Power Loss Recovery POWER SUPPLY RECOVERY MODE In Power Supply Recovery Mode, two power supply cards are installed and connected to a single power source (see Figure 8-2). In this mode, the MX2800 can continue operation in the event of a power supply failure, without interrupting service. The power supplies are load sharing, so either power supply can provide power for the entire unit.
Chapter 8. Power Loss Recovery POWER SUPPLY AND SOURCE RECOVERY MODE In this mode, two power supply cards are installed and are connected to two individual power sources. In this mode, the MX2800 handles any combination of power source or power supply failure. Much like the backup design for the controller cards, the MX2800 is able to internally re-route the power source if a power supply card and the opposite power source fail.
Chapter 8. Power Loss Recovery BATTERY BACKUP MODE With the installation of the ADTRAN Power Supply/Battery Charger (PS/BC) and backup battery pack, the MX2800 is able to continue operation without service interruption in the event of a power outage. This PS/BC (part number 4175043L1) provides -48 VDC to the MX2800. It receives 115 VAC through a standard plug and wall socket. The PS/BC maintains the battery at peak charge (-48 V) at all times.
