Description
The 3RS232a card for Loop-AM3440 series has three interface ports. The DB44 connector is available in Asynchronous and Synchronous modes and provides three ports. One cable supported is for converting from DB44 connector to two DB25 and one DB9 connectors.
For Asynchronous signals, each of the three asynchronous ports up to 38.4 Kb/s rate, is assigned a separate 64 Kb/s channel in independent mode. Moreover, each port can be used in either NON-MUX (independent) mode or MUX mode for Sync/Async applications.
The 3RS232a card comes in two sizes, the longer one is for AM3440-A and C while the shorter one is for AM3440-D and E. Both allow users to transport subrate signals on a 64Kbps channel and the data will fill into the bit stream. Users are able to have customized MUX configuration as wishes. Also, all three ports can be MUXed; only port 1 is in MUX mode at all time, and all the configured MUX ports will be merged to port 1. Furthermore, there will be solely one MUX group and all Mux port kbits cannot be larger than 64kbits.
