Table 2. 2-Wire/4-Wire Multi-Rate Operation

2-Wire Mode
200 kbps to 2.312 Mbps (N × 64
kbps + 8 kbps, where N = 3 to 36)
In 2-wire mode, 8 kbps of
bandwidth is required for overhead
framing
192 kbps to 2.304 Mbps (N × 64
kbps, where N = 3 to 36)
64 kbps to 2.304 Mbps (N × 64
kbps, where N = 1 to 36)
Table
4-Wire Mode
400 kbps to 4.624 Mbps (N × 64 kbps +
16 kbps, where 2 x N = 3 to 36)
In 4-wire mode, 16 kbps is required for
overhead framing.
384 kbps to 4.608 Mbps in 4-wire
mode (2 x N × 64 kbps, where N = 3 to
36)
64 kbps to 4.608 Mbps (N × 64 kbps,
where N = 1 to 72)
This is the actual user data rate deliv-
ered to either the G.703 or Nx64 kbps
ports.
