The PA-MC-E3 is a Cisco multi-channel E3 port adapter with one medium-speed serial interface. The E3 link uses two female BNC connectors, one for receive and one for transmit, and needs 75-ohm coaxial cable with male BNC ends. The adapter splits the E3 stream into four multi-channel E2 data channels and then into 16 E1 lines, at the E3 data rate of 34.368 Mbps.
Each of the 16 E1 lines can be set as channelized E1, PRI ISDN E1, fractional E1 or unframed E1, within a total of 128 logical channels. A channel group holds 1 to 31 time slots, and time slot 16 can be a data channel. Onboard bit error rate test circuitry covers the E1 lines, but E3 testing is not supported. Aggregation of several E1 lines is not done in hardware.
Coaxial loss must stay below 12 dB at 17.184 MHz, and the ideal maximum cable length is 1,300 feet (396.2 meters). The adapter is enabled when it sits in a VIP in Cisco 7000 and 7500 series routers, the Catalyst 6000 FlexWAN module, a Catalyst RSM/VIP2, the Cisco 7304 PCI Port Adapter Carrier Card, or the midplane of a Cisco 7200 series, 7200 VXR, uBR7200 series, 7201 or 7301 router. Look through Cisco interface cards for other WAN port adapters.
