2.2.2 ACS-FRS Firmware Features (62220)
The ACS-FRS firmware release 62220 has the same functionality as the firmware release
62218 except for the addition of circuit priorities. The addition of these priorities will assure
that traffic on higher priority circuits will be unaffected by traffic from lower priority circuits.
Four queues will be implemented so no traffic of lower priority will be allowed to pass when
there is traffic pending in a higher priority queue.
The overall objective is to pass lower priority IP information along with voice traffic without
affecting voice quality. The ACS-FRS card will upon congestion favor the higher priority
queues. Lower priority queues will be buffered and transmitted if bandwidth becomes
available before transmit buffers overflow.
The ACS-FRS card will direct frames according to their DLCI (Data Link Connection
Identifier). IP Datagrams can be terminated on a LAN via the IPR (IP Router) card.
