Description

E1 Span Configure 0x00D8

This message allows the host to configure the transmission format, line length, and SA bits of an E1 span.

NOTE: Before changing span configuration, Cantata ALWAYS RECOMMENDS that you de-assign the spans, assign them again and then send the new span configuration.

Example Message

The following sample message configures an E1 span with the default coding method, signaling method, E1 Layer I management. CRC-4 and FEBE error checking are configured. The default line length, SA Registers, and TS 16 Register are also configured.

NOTES

1. To configure a single node for greater than 64 spans, please contact Cantata technical support.

2. Note that the Cantata message bit-numbering format is 0–7, while the SA Register and TS 16 Register formats are 1–8. Therefore, bit 3 of the host message format is bit 4 of the SA Register and TS 16 Register formats, and so on.

3. This message is backward-compatible to previous software releases.

4. Refer to ITU-T Recommendation G.704 more details on programming SA bits and spare timeslot 16 bits.

5. To use Euro-ISDN Layer 1, you must use an SE1LC Rev. B11 or greater. For more information, refer to the appropriate "Hardware Product Descriptions."

6. For Euro-ISDN compliant E1, set the following:
(Bit 0 = 1) Line format to HDB3
(Bit 1 = 1) CRC
(Bit 2 = 1) FEBE
(Bit 3 = 1) E1 clear Channel
(Bit 5 =1) Euro-ISDN Layer I
Line length to G.703

7. For Austel-ISDN compliant E1, set the following:
(Bit 0 = 1) Line format to HDB3
(Bit 1 = 1) CRC
(Bit 2 = 1) FEBE
(Bit 3 = 1) E1 clear Channel
(Bit 6 = 1) Austel-ISDN Layer I
Line length to G.703

Default E1 Format

The table below shows the default format for E1 spans.You must enable Clear Channel signaling to use timeslot 16 (Channel 30) as a voice channel or for out-of-band signaling (for example, an ISDN application).

NOTE: Clear Channel signaling must be enabled to use timeslot 16 (channel 30) as a D channel in ISDN applications.
