The first connection defined on the board is assigned connection ID 16.
Each successive connection is assigned a successive ID up to the limit of
496 connections.

Raw line connections use connection ID 0 through 15. Each raw line
connection captures full T1 or E1 frames for the same interface number as
its connection ID.

The Endace ERF record format definitions for Type 5 Multi-channel
HDLC Frame Record and Type 6 Multi-Channel Raw Link Data Record
are detailed in Chapter 6 of this document.

3.8 Configuring HDLC RAW Connections

Description

A typical HDLC data stream is bitstuffed with a 0 bit after every 5
consecutive 1s to prevent confusion with the HDLC packet delimiter
(0x7e or 0111 1110).

Configuring for a RAW connection implies that no bit stuffing occurs.

The following section of information describes setting up channel
configurations using

dagchan.

In this section

This section covers the following topics of information.

•

Line RAW Connection ['lr']

•

Channel RAW Connection ['cr']

•

Hyper-channel RAW Connection ['hr']

•

Sub-channel Raw Connection ['sr']
