The EdgeAccess Universal Chassis System Chapter 1 General Description The EdgeAccess Model 2361 is a G.703 compliant T1 fiber optic modem. It is a microprocessorbased modem that supports the standard speed of 1.544Mbps, providing a transparent fiber optic link extension for any metallic T1, regardless of line coding. Figure 1. The Standalone 2361 Modem Figure 2. The Rackmount 2361 Modem Figure 3.
The EdgeAccess Universal Chassis System 1.1 Product Description The 2361 modem contains three main components: • Main Module The modem's main module consists of CPU modem management hardware, I/O control and memory, a custom composite XL Mux/Demux device (gate array), Loopback Support Circuitry, Message Bus, Redundancy Interface Units, and Front Panel Indicators and Switches. • Electrical Line Interface Module (ELIM): An I/O Module available in a variety of electrical interfaces.
The EdgeAccess Universal Chassis System 1.1.2 Redundancy The 2361 provides two redundancy configuration types. In one type, only two modems are used, but the fiber between them is duplicated. The other type requires four modems and two complete fiber paths. Fiber Path Redundancy: Two pairs of fibers are run between two modems. Only the fiber, therefore, is redundant. Failure of one fiber pair causes a switchover to the other pair. A special redundant OLIM is required for Fiber Path Redundancy.
The EdgeAccess Universal Chassis System 1.1.5 Diagnostic and Test Functions The 2361 modem provides complete Loopback feature, Continuous Self Test, and extensive link and Bit Error Rate Testing. 1.1.6 Standalone Modem The standalone version comes in a compact enclosure for desktop, shelf, rack, or wall mount installations. It has a built-in AC or DC power supply and utilizes the same ELIMs and OLIMs as the rackmount version.

The EdgeAccess Universal Chassis System 1.3 OLIM Interface Options There are several options for selecting optical transceivers.
The EdgeAccess Universal Chassis System 1.5 2361 Modem Operating At E1 Rate While the 2361 modem is a T1 modem, it can also function in E1 mode. This can be accomplished by changing a switch position on the Main Module. For Rackmount modems, remove the modem from the chassis, and locate the T1/E1 switch on the board. Then, change the switch to E1. For a standalone modem, the switch is accessible by removing the ELIM or OLIM, reaching inside between the ELIM and the OLIM, and toggling the switch. Figure 8.

The EdgeAccess Universal Chassis System 4.4.6 Configuring Modem Traps Traps are conditions that require management attention, and are routed and recorded via software to the Network Manager. This could be, for example, an SNMP-based management system set up by the plant system administrator. Traps are logged, compiled and saved, viewed via software screens, and are not sent electronically to alarm relays for shop-wide notification. Note: The Trap feature requires SNMP.
The EdgeAccess Universal Chassis System Table 6 describes the function of each trap: Table 6: Alarm Trap Option Definitions Name Function 1.
The EdgeAccess Universal Chassis System Chapter 5 Diagnostics The 2361 modem has several diagnostic test options for determining the source and cause of data transmission errors. Some of these tests are being performed automatically while others require a test technician. 5.1 Link Self-Test The Link Self Test, also referred as the auxiliary BERT, is continuously running on a free and reserved channel on the fiber optic payload A trap message will go out when the error count goes from 0 to another number.
The EdgeAccess Universal Chassis System 2. This screen reports the number of link errors for both the local and remote modems. Errors counted here listed below: • • • • • • • • Composite LOS Errors Electrical LOS Errors Electrical AIS Errors SQL Primary Errors Optical Transmit Errors SQL Secondary Errors Link Self Test Errors Link Self Test LOS To determine the number of errors, reset the errors to zero and allow errors to accumulate, helping you determine which modem or link has a problem.
The EdgeAccess Universal Chassis System 5.4 Loopback and Bit Error Rate Testing The Diagnostics Screen, as shown in Figure 31, can be accessed from both the standalone and rackmount modems. Diagnostic testing can be performed on the local modem and its secondary redundant partner. Remote modems show the status of the diagnostic performed. Figure 33. Diagnostics Screen Provides Access to BERT and Loopback Testing From the Modem Main Menu type "2" to access the Diagnostic screen.
The EdgeAccess Universal Chassis System • Remote BI Remote electrical interface looped back. Remote signals looped back on the fiber side as well. In a Bi-directional Loopback (Local BI and Remote BI), data is looped back in both directions, assuring a stricter standard of error checking. • Local Both Both local and remote modems have their electrical interface looped back. • Clear All This clears all the loopbacks on the local and remote units.
The EdgeAccess Universal Chassis System 5.4.1 Normal Operation In normal transparent operation, the data from the user equipment enters the modem at its transmit interface, passes through the proprietary fiber optic network (See Figure 35), outputs at the receive interface on the remote end, and vice versa. LIU Logic Fiber Optical Link Rx MuxEnc Tx DemuxDec Fiber Logic LIU DemuxDec Tx MuxEnc Rx Normal Operation Figure 34. The Modem in Normal Operation 5.4.
The EdgeAccess Universal Chassis System 5.4.3 Remote Loopback When activated, the Remote Loopback test will cause all data transmission from the local user device to be looped back after the data Decoder/Encoder functional block in the remote modem. The remote modem under local loopback will transmit AIS to T1/E1 Line Interface (See Figure 37). LIU Logic Fiber Rx MuxEnc Tx DemuxDec Optical Link Fiber Logic LIU DemuxDec Tx AIS MuxEnc Rx Figure 36. The Modem in Remote Loopback Operation 5.4.
The EdgeAccess Universal Chassis System 5.4.5 Local Bi-directional Loopback When activated, the Local Bi-directional Loopback test will cause all data transmission from the local user device to be looped back toward the receive side of that same device. At the same time, all data transmissions from the remote unit will be looped back towards the transmit side of the same device (Figure 39). LIU Logic Rx Fiber MuxEnc Optical Link DemuxDec Tx Fiber Logic LIU Tx DemuxDec MuxEnc Rx Figure 38.
The EdgeAccess Universal Chassis System 5.4.7 Local Loopback at Both Ends When this loopback is activated, it will cause all data transmission from the local user device to be looped back toward the receive side of that same local device. At the same time, all data transmissions from the remote unit will be looped back towards the receive side of the remote device (as shown in Figure 41).

The EdgeAccess Universal Chassis System Chapter 6 Troubleshooting Troubleshooting can be a very simple and easy task if discrete logical steps are taken. This chapter addresses potential problems and how to take corrective action. The front panel LEDs display the majority of fault conditions. These and other conditions also appear in System Alarms screen, Hardware Configuration screen and Functional Configuration screen.
The EdgeAccess Universal Chassis System 6.2 Fiber Optic Related Problems CLS and SQL LEDs are fiber optic cable related indicators. In normal operation, CLS should be OFF and SQL should be green. SQL Red LED indicates that the optic signal levels are below the threshold, while CLS Red LED indicates composite signal loss. If both LEDs are RED, this indicates a failure in the fiber optic cable. In this event, proper steps should be taken to correct the failed optic cable.
The EdgeAccess Universal Chassis System 6.4.2 Repeated Resets If the modem resets by itself, it could be because of a Watchdog condition. If it resets repeatedly, contact Canoga Perkins, Technical Support. 6.4.3 ELIM Switched with OLIM If the ELIM is in the OLIM designated slot and vice versa, the LEDs on the module face plate will not light up. Please refer to the Configuration Error line of the System Alarms screen to verify the following and take corrective action by switching them around.
The EdgeAccess Universal Chassis System 6.5 Replacing Modules When you have replaced a Line Interface Module or an entire modem, possible configuration errors may surface, turning the CFG indicator red. This condition may most likely be the result of software version incompatibility. You can verify this by going to the System Alarms screen where the Configuration Error line will show"OS.
The EdgeAccess Universal Chassis System 6.8 Intermittent Problems in Data Transmission 1. Check the AIS LED on the ELIM. If Amber, the modem is receiving "all 1's." 2. Check the Alarm Indication Signal line on the Alarm Systems screen. If it says "YES," then the modem is receiving AIS. Check the connecting equipment for proper setup. 3. To verify errors received by the modem, start a session with the Link Error Counter screen. Every modem in the link will appear on this screen.

The EdgeAccess Universal Chassis System Chapter 7 Redundant Configurations For critical circuits where downtime cannot be tolerated, redundant configurations are used. In a redundant configuration a secondary (inactive), circuit is ready to begin transmitting data. Should there be a problem on the active circuit. For example, if the system detects loss of signal, the secondary circuit will take over the actual data payload. Personnel can freely troubleshoot the problem without disrupting data transmission.
The EdgeAccess Universal Chassis System Full Modem Redundancy: The entire modem hardware, each with its own fiber path, is made redundant, as shown in Figure 40: Fiber Figure 42.
The EdgeAccess Universal Chassis System Figure 43. Redundancy Circuit Diagram 7.
The EdgeAccess Universal Chassis System Important: Remember that the rackmount modems must be placed in a special slot configuration, as follows: • The primary modem must be placed in an odd slot • The secondary modem must be placed in the even slot to its immediate right. Example: Slot 3 must be paired with slot 4, and slot 7 must be paired with slot 8. In such a configuration, the modems in slot 3 and 7 would be primary, and the modems in slot 4 and 8 would be secondary. 7.1.
The EdgeAccess Universal Chassis System 4. Use the Space Bar to toggle through each option (outlined below). 5. Use the Tab key to change redundancy options for Local and Remote, Primary and Secondary Modems. 7.2.1 Redundancy Mode Options Below is an explanation of each redundancy mode option. Note that when a redundant configuration is detected and this screen is accessed, the program will automatically display "Auto," defaulting to the automatic redundancy setting.
The EdgeAccess Universal Chassis System This is done because the chassis backplane bus between adjacent odd and even slots, insures that when a redundant configuration is set up, data is exchanged between the primary and secondary link. Active Modem: Inactive Modem: The active modem is the modem transmitting the data payload. The following conditions exist in the active modem: • ELIM Relays are closed. The electrical signal is making it to the composite. • STA LED Solid green.
The EdgeAccess Universal Chassis System A modem can be manually switched from inactive to active for the following reasons: 1) To bring the modem into standard use. 2) To test with a full data payload for quality verification purposes. 3) To track down an unknown, intermittent error, and determine if this modem is the source of it. Note: Switching from redundant mode to a non-redundant modem mode does not require that you replace the redundant ELIMs.

The EdgeAccess Universal Chassis System Chapter 8 Upgrading Modem Software The 2361 modem has two flash memory banks for storing firmware: • The Active Flash Memory Region. The active region is operative while the modem is running. • The Inactive Flash Memory Region. Software upgrades are downloaded here, and swapped with the firmware in the active region. Since downloading a software upgrade can take some time, software is downloaded to the inactive region.
The EdgeAccess Universal Chassis System 8.1 Determining Current Software and Version Availability To determine the current software version used by the modem, do the following: 1. From the Modem Main Menu, type "6" to access the Software Upgrade Screen. 2. View the Active Firmware and Inactive Firmware versions. If applicable, local and remote, primary and secondary modems each will report Firmware versions at this screen. 3. Write these version numbers down.
The EdgeAccess Universal Chassis System 8.3 Installing the New Software Instructions for installing software into the rackmount modem (in a UCS Chassis) via DMM will differ from installing into a standalone modem. 8.3.1 Installing in a Managed UCS Chassis For these instructions, please refer to the DMM users manual. 8.3.2 Installing into a Standalone Modem Via TFTP This installation is performed over the dial-up network and requires that the standalone modem has the SNMP option.
The EdgeAccess Universal Chassis System Note: The last three digits of the filename indicate the version number. For example, 2X6X0173.zip indicates firmware version number 1.73 is to be downloaded. Also, 2X6X0115.bin indicates bootcode version 1.15 is to be downloaded. 8. Follow the on-screen prompts for downloading the file. 9. "Download in progress, please wait," is displayed. CAUTION: Make sure the unit is not reset or powered down at this time.
The EdgeAccess Universal Chassis System • The firmware upgrade file has a .zip file extension. (Do not unzip this file. Downloading it will automatically expand the files appropriately.) To install the new version, do the following: 1. First, download the new firmware or bootcode version from Canoga Perkins website to your server's root directory. 2. Put the dwnfirm.exe program (a single executable file) in the same folder as the firmware or bootcode version just installed. 3.
