Speeds of 128Kbps | ZyXEL Communications omni series specification

Speeds of 128Kbps

BRI ISDN consists of three (2B+D) logical channels. Each B channel can be used independently for a dial-up connection running at 56Kbps or 64Kbps (bits per second).

The two B channels can be used together for a single data connection to provide 112K (with In-Band Signaling) or 128K (when Out-of- Band Signaling is used). It is called a “Bundle Connection”.

The type of channel bundling described in the V.120 section is supported only between the following ZyXEL products: omni.net series, Omni TA128, or Elite 2864I, and uses Multiple Link Protocol (MLP) and “cFos” channel bundling (CCB).

Identifying your line provisioning

For bundled connections, the two B channels of your ISDN line must be able to handle data circuit switch connections with unrestricted 64K or 56Kbps line speeds. Two separate data calls will be established consecutively.

Making a Bundled Call with V.120

A bundled V.120 connection is initiated at the calling site when ATB20 (B channel protocol V.120) has been selected and the channel bundling mode has been enabled by an AT&J3 command. The channel bundling command (AT&J3) must be set on both the calling and receiving sides, otherwise a single channel connection will be made.

Type:

ATB20<Enter> (Set B channel protocol to V.120)

AT&J3<Enter> (Set the TA to make a bundled call)

Type:

AT&WZ<Enter> (If you want to save the setting)
