INTRODUCTION

1.5 CSMIM-T1 OVERVIEW

The CSMIM-T1 is a dual-slot, Annex Software compatible system designed to reside in the MMAC series of hubs. The module takes the existing CSMIM2 core and adds enhanced processing power in the form of dual 486SXLC2-40 clock doubled processors. Both the main and secondary processors have been upgraded, which allows the main processor to control the MMAC network interfaces, while the second controls the serial ports. These processors have access to a minimum of 4 MB DRAM (standard), but may be upgraded to 8 MB through the installation of SIMM modules. This memory is shared between the processors, and arbitrated on a cycle by cycle basis.

Extensive power up diagnostics are provided to conﬁdence check the system prior to the loading of application software. A Console Port is used for system setup, booting, and diagnostic purposes. After booting, the Console Port is idle. System boot is accomplished either from a UNIX host, a VAX VMS host, or an optional Flash PROM. If you are operating from Flash only , be aware that host based services such as security are supported. If you have any questions, contact Cabletron Technical Support.

not

It should be mentioned that although the CSMIM-T1 is capable of running in a Novell environment, it will not boot from a Novell server. In a Novell environment, the module must be booted either from a UNIX server, or from Flash.

There are 24 V.34 modems in the CSMIM-T1. Access for the T -1 network is provided by a single RJ48C connector on the front panel. Data received from the T-1 network is either moved through the CSMIM-T1 module and onto the Ethernet backplane, or fed back out through the Drop and Insert Interface on the front panel. An example of this would be connecting the Drop and Insert Interface to a PBX for voice applications.

Ethernet Channel Indicators

There are three green LEDs that indicate the Ethernet channel (A, B, or C) that is selected by either the software or by jumper conﬁguration.

1.6.3 The SET UP Switch

The SET UP Switch allows the user to change the operational mode of the module from normal to set up. When the module powers up, it automatically enters the normal mode. To enter the SET UP mode, the SET UP switch must be depressed within 30 seconds of power-up. When the S/U LED lights, the unit is in the SET UP mode.

Depressing the SET UP Switch at any time for approximately three seconds causes the module to enter a RESET state. This is the equivalent of a reboot. The green S/U LED will ﬂash while the unit executes power up diagnostics, and the SET UP mode can be entered.

Chapter 1:

INTRODUCTION

1.6.4 T-1 Network Access

There are two ports on the front panel that allow access to the T-1 network. The T-1 Network Interface Port is an 8-pin, RJ48C port that provides access for the digital T-1 line. The Drop/Insert Interface is also an 8-pin, RJ48C port, and provides connection to a local Private Branch Exchange (PBX), or other equipment, such as an ETWMIM equipped with a T-1 interface.

In addition to these ports, there are 8 Status LEDs that provide the user with valuable information regarding the T-1 network.

DI SYNC

The green DI SYNC LED is ON when the T-1 engine is detecting frame synchronization on the Drop and Insert Interface. The LED is off when there is a Loss of Frame (LOF) synchronization.

An LOF condition causes the T-1 engine to transmit all unframed ones (keep alive signal) to the device attached to the Drop and Insert Interface.

ON LINE LED

The green ON LINE LED is ON when the T-1 engine is connected to the network interface.

1.6.5 NETWORK STATUS / ALARMS

TEST - Network Test

This red indicator is ON when the T-1 engine network interface is placed into a test loopback condition. Loopback tests are activated either locally by the user, or by the telco provider.

SYNC - Synchronized

This green indicator is ON when the T-1 engine is properly synchronized with the network signal and is receiving proper framing information.

LOS - Loss of Signal

This red indicator is ON when the T-1 engine is detecting no signal (pulses) on the network interface receiver. When a LOS condition exists the T-1 engine transmits unframed all ones (Alarm Indication Signal) to the network.

1-8 CSMIM-T1 Hardware Installation Guide

CSMIM-T1 Front Panel

RED - Red Alarm

This red indicator is ON during a locally detected carrier failure. During the “red” alarm condition, a “yellow” alarm is transmitted to the telephone network.

YEL - Yellow Alarm

This yellow indicator is ON when receiving a “yellow” alarm condition from the telephone network.

BLU - Blue Alarm

This blue indicator is ON when receiving an unframed, all ones Alarm Indication Signal (AIS) from the network. This condition exists upon a loss of originating signal, or when any action is taken that would cause signal disruption.

1.6.6 Modem Conﬁguration Status LEDs

To help determine if a problem exists in a modem, there are three green/amber LEDs labeled 1-8, 9-16, and 17-24. These LEDs indicate groups of modems installed. When amber, the LED indicates that at least one modem within the indicated group is in a fault condition. When green, the LED indicates that diagnostics have determined that the modems are operating normally.

1.6.7 Modem Port Status LEDs

Each modem has a group of three LEDs to indicate activity. These LEDs can help determine a fault within a group of modems.

CD - Carrier Detect

This green LED is ON when the carrier has been detected on the telephone line of the corresponding modem. There are a total of 24 CD indicators, one per channel.

TX - Transmit Data

This green LED ﬂashes to indicate the corresponding modem is transmitting data. There are a total of 24 TX indicators, one per channel.

RX - Receive Data

This green LED ﬂashes to indicate the corresponding modem is receiving data. There are a total of 24 RX indicators, one per channel.

Chapter 1: INTRODUCTION

1.6.8 EFS Key Number

The sticker on the front panel next to the serial number is the EFS Key. This key is factory loaded and enables all options on the module. The EFS value is stored in the EEPROM, and will be erased when executing the “erase” command. It is important that you record this value, in the event you need to clear the EEPROM. To re-enter the key value, refer to the procedure in Chapter 2, section 2.7.3.

1.7 CONNECTIVITY

Ethernet Interface Selection

The CSMIM-T1 has a 48 pin DIN connector for connection to the A Channel Ethernet segment, and a 96 pin DIN connector for B and C channel attachment. Segment selection is performed by setting jumpers, but may be overridden by commands from the MMAC management module.

Jumper position and channel selection is explained in Chapter 2, Installing the CSMIM-T1.

1.8 TELCO CONNECTION INFORMATION

There are different ways the CSMIM-T1 can be set up. It can use either a full T-1 line, or a fractional one. In either case, there is speciﬁc information the user needs to get from and provide to the Telco providing the connection. This section supplies some of the basic information necessary to set up a T-1 connection.

1.8.1 Connecting the CSMIM-T1 to a Full T-1 Line

In a full T-1 application, all channels of the line are used in the same manner, such as data lines for multiple computer ports. There is no peeling off of any channels, and the Drop and Insert Port is not used. Table 1-1 provides a short list of information necessary to conﬁgure a full T-1 circuit in a Point-to-Point Protocol (PPP) environment. Conﬁgurations may vary depending on the application.

1.8.2 Connecting the CSMIM-T1 to a Fractional T-1 Line

In a fractional T-1 setup, only a portion of the 24 timeslots or DS-0’s are used. Some may be routed through the Drop and Insert Port to a PBX, as in a voice application. Table 1-2 provides a short list of information necessary to use a fractional T-1 circuit in a PPP environment. Conﬁgurations may vary depending on the hub. The line conﬁguration information shown in Table 1-2 must be supplied by the service provider.

2.2 LOCATING THE ETHERNET JUMPERS

The CSMIM-T1 has a single jumper block that contains two Ethernet jumpers and one Subnet jumper. Figure 2-1 shows the locations and jumper numbers for the Ethernet and Subnet jumpers. Please note that the jumpers are located on the Main Processor Board, not the modem board.

Locating the Ethernet Jumpers

2.2.1 Setting the Ethernet Jumpers

The Ethernet jumpers determine how your CSMIM-T1 operates on the network. You can set the jumpers so that the CSMIM-T1 operates on channel A, B, or C. Refer to Figure 2-1 to locate and configure the jumpers.

There is a single jumper block, labelled J12, that is used to select both the Ethernet Segment and the Subnet. Pin row A at J12 is used to select the Subnet. Pin rows B and C are used to select Ethernet Channels. Please use care in configuring the jumpers. Figure 2-1 shows the default settings (Channel B) for the CSMIM-T1.

To operate on Channel A: Place jumpers over the center pin and pin 3

•

in pin rows B and C.

• To operate on Channel B: Place one jumper over the center pin and pin

3 in pin row B, and the other jumper over the center pin and pin 1 in pin row C.

T o operate on Channel C: Place one jumper o ver the center pin and pin

•

1 in pin row B, and the other jumper over the center pin and pin 3 in pin row C.

2.2.2 Setting the Subnet Jumper

The CSMIM-T1 allows grouping of the B and C channels into a subnet to provide additional Ethernet networks. All MIMs in the MMAC to the left of the CSMIM-T1 become isolated on the B and C channel FNB connector. These additional networks cannot communicate over the B and C channel FNB connector with any module to the right.

NOTE

CSMIM-T1 Hardware Installation Guide 2-3

Ethernet Channel and Subnet jumper settings can be overridden by an EMME or EMM-E6 installed in the MMAC.

Chapter 2: INSTALLING THE CSMIM-T1

To set the Subnet jumper, refer to Figure 2-1 and configure pin row A of J12 as follows:

•

Normal Operation (maintain continuity of the backplane: Default):

Place a jumper over the center pin and pin 3 in pin row A.

• Subnet mode: Place a jumper over the center pin and pin 1 in pin ro w A.

2.3 NETWORK BYPASS JUMPER

The CSMIM-T1 has an internal jumper that is used to select a bypass mode for the T-1 Engine. The T-1 engine will go into a bypass mode when the MMAC hub is po wered down, reset, or when the CSMIM-T1 module is removed from the hub . This jumper is labelled J24, and is located on the modem board, just behind the T-1 Network Interface port (See Figure 2-2).

The jumper can be set to Network Loopback Mode (default setting) or Bypass Mode. Please check your module to see that the jumper is

conﬁgured in the default setting before installing into your hub. Network Loopback Mode loops back all signals on each interface. The Bypass Mode will connect the DSX1 lines directly to the DS1 lines.
