The PA-A6-OC3MM is the Cisco 1-port ATM OC-3c/STM-1 multimode port adapter in the enhanced PA-A6 family. Its port runs at 155.52 Mbps over 62.5/125-micron multimode fiber with an SC connector at 1270 to 1380 nm, for links up to 2 km.
Optical transmit power is -20 to -14 dBm and receive power is -30 to -14 dBm, with a power budget of 9 dB. The single-mode OC-3c/STM-1 adapters in the family are the PA-A6-OC3SMI at 15 km and the PA-A6-OC3SML at 45 km, and the DS3 and E3 adapters are the PA-A6-T3 and PA-A6-E3.
ATM service classes are UBR, VBR-nrt, ABR, CBR and VBR-rt, and traffic shaping works per virtual circuit and per virtual path, with peak and sustainable cell rate from 56 kbps to line rate in 2.29-kbps steps on OC-3c/STM-1. AAL5 serves data, AAL2 serves voice on the Cisco 7200, and ATM Forum UNI 3.0, 3.1 and 4.0 signaling, LANE 2.0, MPLS and per-VC queuing are supported.
Host platforms 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. More port adapters are in Cisco interface cards.
