5.3.3.7 Framing

The WAN port may be configured to operate in the following modes

For E1 mode

Unframed

Clear channel, 2.048Mbps

Framed

G.704 Framed, 1.984Mbps payload

Fractional

G.704 Framed, Nx64

For T1 mode

Unframed

Clear channel, 1.544Mbps

Framed

ESF/D4 Framed, 1.536Mbps payload

Fractional

ESF/D4 Framed, Nx64

Following a cold start, the default setting is determined by the position of bit switch 4,
which can select between framed and unframed modes.

5.3.3.8 CRC-4 (E1 Only)

When operating in Framed or Fractional mode CRC-4 multiframe mode may be enabled or
disabled.

5.3.3.9 sigNalling (E1 Only)

When operating in framed mode, the signaling option determines whether timeslot 16 is
available for payload. With Signalling Enabled timeslot 16 is not used for payload giving a
link capacity of 1.920MBps rather than 1.984MBps.

5.3.3.10 Multi-Frame (T1 only)

When in T1 mode, the framing mode may be either

Multiframe

ESF

Extended Multiframe
