The PA-A6-E3 is a Cisco 1-port ATM E3 port adapter in the enhanced PA-A6 family. The E3 interface runs at 34.368 Mbps over 75-ohm coaxial cable with a BNC connector, for links up to 1250 feet. It is a single-width port adapter.
The adapter supports 8191 ATM virtual circuits, with ATM service classes ABR, VBR-nrt, VBR-rt, CBR and UBR. Traffic shaping works per virtual circuit and per virtual path, with peak cell rate and sustainable cell rate from 56 kbps up to line rate in 0.515-kbps increments on the E3 interface, and maximum burst size from 1 to 65535 cells. AAL5 serves data, and AAL2 serves voice on the Cisco 7200 with E3 interfaces.
Supported hosts are the Cisco 7200 and 7200VXR series with NPE-400 and above, the 7301 and 7304, the FlexWAN module in the Cisco 7600, and the Cisco 7500 with VIP4-50, VIP4-80 or VIP6-80. The 7200VXR and 7301 need Cisco IOS 12.2(15)T or 12.3 Mainline and later, the 7304 needs 12.2(31)SB, and the 7500 VIPs need 12.3(1) and later.
LAN Emulation, IP-to-ATM class of service, VoATM and FRF.8/FRF.5 interworking are supported. Other adapters in the family are the PA-A6-T3 (DS3) and the OC-3c/STM-1 models, and more are in Cisco interface cards.
