Page 6: Chapter 1: Description And Requirements
Chapter 1: Description and Requirements Chapter 1: Description and Requirements The E3Switch converters described herein are used in pairs to connect two Ethernet LANs via either one or two E3 or T3/DS3 links at up to 88Mbit/s actual user data rate per direction. The LAN interface is RJ45 100/1000BaseTX copper or SFP 1000BaseX fiber optic. -
Page 7: Chapter 2: Quick Set-Up
Chapter 2: Quick Set-up Chapter 2: Quick Set-up Attach the converter to a power source. The front panel lights should illuminate. Green is normal; orange indicates an error. Attach an Ethernet UTP5 cable from your LAN equipment to the RJ-45 LAN Port 2. The converter can perform automatic cross-over vs straight-through cable adaptation. -
Page 8: Chapter 3: Front Panel
Chapter 3: Front Panel Chapter 3: Front Panel Front Panel Indicators All Indicators: Green indicates normal operation. Orange indicates an error condition. Black indicates a disabled port. DS3/E3 1/2: Green if the unit has synchronized to a valid carrier signal pattern from the remote unit and data can be transferred on the link. -
Page 9: Automatic Link-Local Ip Address
Chapter 4: Remote Management HTTP and SNMP Other than the e3switch.local addresses described below, all IP addresses used within the converter's management interface must be in xxx.xxx.xxx.xxx numeric format rather than a human-readable DNS- resolvable hostname. Automatic Link-Local IP Address E3Switch converters are shipped with an initial IP address that conforms to recent zero-configuration link- local standards. -
Page 10: Management Passwords
Chapter 4: Remote Management HTTP and SNMP Management Passwords Note: In order to log in with Internet Explorer 7+ or if difficulty occurs when logging in with credentials known to be valid, firmware prior to October 18 , 2007 must be upgraded to ameliorate a new feature present in IE7 authentication messages. -
Page 11: Http Management
Chapter 4: Remote Management HTTP and SNMP Variables in the groups: interface, ds3, dot3 & mau, control the link datapath; allowing write access allows disabling the link. Specific variables disabled for all write users are secure. Specific statistics disabled for all read users are invisible and secure. -
Page 12: Feature Activation/Upgrade
Chapter 4: Remote Management HTTP and SNMP Firmware upgrades may be transferred to the converter via the LAN port (or DS3/E3 port, if management of the remote converter is enabled). A hardware reset, which will interrupt link data flow for several seconds, will be required at some point after the transfer in order to begin using the new firmware. -
Page 13: Packet Flow
Chapter 5: Operating Modes and Configuration messages are transmitted in the C-Bits of the frame and do not decrease bandwidth available for data. PMDL Circuit ID messages facilitate confirmation of the data source when presented with a pair of unlabeled BNC cables. Packet Flow Packet Order and Channel Bonding/Aggregation On single-telecom converters, LAN packet delivery order is guaranteed with the exception that high-priority... -
Page 14: Lan-To-Lan
Chapter 5: Operating Modes and Configuration Packets arriving at one telecom port will not be passed out the other, so it is not possible to use one dual- channel converter in a 3-unit topology at the junction of a Y or V; use two converters at such a junction with a LAN switch or router to properly control traffic flow to the branches of such a topology. -
Page 15: Lan Port Speed
Chapter 5: Operating Modes and Configuration LAN Port Speed 1000Mbit/s LAN speeds are only available if firmware enabling the SFP port option or GbE LAN has been purchased. 100Mbit/s is generally preferred over 1000Mbit/s, which generates significantly more power-requirements, heat, and radiated noise even in the absence of packet flow. 1000Mbit/s may slightly reduce path latency, as an incoming LAN packet must be fully received before being forwarded to an outgoing port. -
Page 16: Oip / Video Or High -C O S Priority Frames
Chapter 5: Operating Modes and Configuration As shipped, the unit will accept management packets with any VLAN tags and attempt to respond to the same. For more robust performance, specific VLAN tag settings can be configured. These settings only apply to packets to and from the converter's management entity. VLAN tags in packets destined for the DS3/E3 link are passed unaltered. -
Page 17: Autonegotiation Problems
Chapter 6: Interoperability If LAN equipment appears to disable a port connected to the converter, be aware that “sophisticated” routers and switches will often disable a LAN port if data being sent appears similar to data or MAC addresses being received, as is the case in telecom loopback. Autonegotiation problems There are rare cases with older LAN equipment in which it may be necessary to disable autonegotiation. -
Page 18: Routers And Switches
Chapter 6: Interoperability Routers and Switches Be aware that during DS3/E3 loopback testing, “sophisticated” routers and switches will often disable a LAN port if data being sent appears similar to data or MAC addresses being received. This can cause confusion. Chapter 7: Telecom Connections Framing and Physical Link The converter can transmit the LAN data over a variety of E3, T3/DS3 links (with the appropriate media... -
Page 19: Lan Cabling
Chapter 8: LAN Connections and Performance There are rare cases with older LAN equipment in which it may be necessary to disable autonegotiation. If crc-errors or short packet errors are seen in the management statistics of the LAN port, the attached LAN equipment has probably configured itself to half-duplex mode and colliding packets are being lost. -
Page 20: Tcp/Ip And General Performance Tuning
Chapter 8: LAN Connections and Performance reassembly order is guaranteed (with bypass of high-CoS traffic) if configured in “bonded” mode (on firmware beginning March 2008). For “load-balance” configuration, or on firmware shipped before March 2008, packet order is generally maintained but not guaranteed. Refer to the configuration section of this document for further discussion. -
Page 21: Loopback Of Ds3
Chapter 10: Troubleshooting The next most frequent source of problems generally arises from faulty cabling or connectors or incorrect cable type. Cabling must be UTP5 or better for LAN and 75-Ohm rather than 50-Ohm for telecom. If long telecom cable runs or an electrically noisy environment exists, high-quality coaxial cable will be required. The least frequent cause of problems will be the hardware of the converter itself. -
Page 22: Alternatives To Loopback
Chapter 10: Troubleshooting local loopback using a short DS3 cable, since connectors and cables are a much more likely source of problems. Local loopback can also often result in LAN equipment attached to the converter to immediately disable the LAN port as a flood-prevention measure. •... -

Chapter 10: Troubleshooting ▪ snmpset -v 1 -c public <ip-address-of-unit> .1.3.6.1.2.1.10.30.5.1.9.6 i 1 (terminates loopback as in dsx3NoLoop(1)) ▪ snmpget -v 1 -c public <ip-address-of-unit> .1.3.6.1.2.1.10.30.5.1.9.6 (returns current loopback value of DS3 Port 2) • SNMP FEAC Initiation: See above for VACM MIB write-access description first. An SNMP request can set the local converter's dsx3SendCode variable to dsx3SendLineCode, which requests the remote converter to loopback DS3 data received. -
Page 24: Step-By-Step Diagnosis
Chapter 10: Troubleshooting The default ping generates approximately one 64-byte packet per second. This is not a robust test. If convenient, locate a ping program or set command line parameters to generate perhaps 50 pings per second and try both small packets and large 1400-byte packets. Be aware that packets larger than 1400 bytes sometimes uncover bugs in the software of ping programs. -
