Configuring the RLC
IP Bandwidth calculation examples (using Peak Data Rate values):
For a one Mbyte Frame Relay WAN supporting only G.711 calls, enter 848
in the IP Bandwidth field according to the following calculation:
1024K (1 Mbyte) - 16K for signaling = 1008K of available bandwidth
1008K/76Kbps (peak data rate for a G.711 call according to the Bandwidth
Usage table) = 13
therefore,
IP Bandwidth = (13 G.711 calls * 64K [required voice bandwidth from the
table above]) + 16K (for signaling) = 832 + 16 = 848K
For a one Mbyte Frame Relay WAN supporting only G.729A calls, enter 0
in the IP Bandwidth field according to the following calculation:
1024 (1 Mbyte) - 16K for signaling = 1008K of available bandwidth
1008/20Kbps (peak data rate for a G.729A call according to the Bandwidth
Usage table) = 50
therefore,
IP Bandwidth = (50 G.729A calls * 8K [required voice bandwidth
according to the table above]) + 16K (for signaling) = 400 + 16 = 416K
Note: Since the maximum number of simultaneous calls possible through a
Remote Gateway 9100 Series system is 32 calls, 50 simultaneous calls are
not possible. Therefore, the proper IP Bandwidth setting is 0. Zero (0) is
the setting for no bandwidth limit.
For a 128K Frame Relay WAN supporting up to two G.726 and one G.729A
call, enter 88 in the IP Bandwidth field according to the following
calculation:
(2 calls * 44K [peak data rate for a G.726 call according to the Bandwidth
Usage table]) + (1 call * 22K [peak data rate for a G.729A call according to
the Bandwidth Usage table]) + 16K (for signaling) = 88 + 22 + 16 =126K
therefore,
IP Bandwidth = (2 G.726 calls * 32K required voice bandwidth from the
table above) + (1 G.729A call * 8K required voice bandwidth from the table
above) + 16K (for signaling) = (2 * 32) + (1 * 8) + 16 = 64 + 8 + 16 = 88K
