Chapter 1: description and requirements chapter 1: description and requirements the e3switch tdm-over-psn pseudowire gateways described herein are used in pairs to extend a full or fractional e3 or t3/ds3 tdm circuit over an intermediate ethernet layer-2 packet switched network (psn). The tdm circui...

Chapter 2: quick set-up chapter 2: quick set-up attach the gateway 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 gateway can perform automatic cross-over vs s...

Chapter 4: remote management http and snmp chapter 4: remote management http and snmp gateways contain both an http management interface, which may be accessed via a web browser, and an snmpv2c agent. Unit's ip/mac address the source ethernet mac address of e3switch gateways is 00:50:c2:6f:xx:xx. Th...

Chapter 4: remote management http and snmp the following methods may be used to determine a gateway's ip address if lost or forgotten. Note that once determined, management communication with the unit may only be possible from a host configured to the same ip subnet address if the unit's default rou...

Chapter 5: operating modes and configuration packet flow packet order 802.1p class of service (cos), and diffserv when appropriate, levels are configurable to ensure timely delivery of tdm packets through the lan. While traveling across packet switched networks, received packets may arrive out of se...

Chapter 5: operating modes and configuration port to port packet flow lan-to-lan full lan-to-lan packet flow can be enabled on a unit, if desired. This might be useful if it was desirable for incoming sfp management packets to exit the copper lan port 2 of the unit, along with the packets carrying t...

Chapter 5: operating modes and configuration sfp second lan port the sfp lan port 1 hardware exists on all gateways shipped and allows an sfp transceiver to enable out- of-band management, through either lan port, or fiber-optic lan connections of 10km or more. Refer to interoperability section of t...

Chapter 10: troubleshooting the least frequent cause of problems will be the hardware of the gateway itself. This statement is not due to a narcissistic point of view, but rather to the simplicity of configuration features on the gateway and the low-component count. A microwave radio link, for examp...

Chapter 10: troubleshooting 3. Ensure a proper lan cable is being used. Straight-through or crossover cabling is acceptable. The lan light of the gateway port to which any lan is attached should be illuminated and green. If not, ensure that the attached equipment is set for autonegotiation and can a...
