Operation Modes

IPmux-1 E1/T1

IPmux-1 E1/T1 operation modes are:

• Unframed

• Fractional

• Fractional with CAS.

Unframed

In the transparent mode, the incoming bit stream from each channel (regardless of

framing) is converted into IP over Ethernet frames. This option provides clear

channel end-to-end service (unframed).

Fractional

In the fractional mode, the incoming bit stream is regarded as a sequence of

n x 64 kbps channel groups (according to framing). Each predefined group of

channels is converted into a structure block. The structure block is packetized into

IP frames and transmitted.

This mode allows transmission of several selected timeslots without the whole E1

or T1 frame, as in transparent mode.

Use Fractional mode when grooming ISDN BRI channels from a remote IPmux-1E

unit.
