Duall Access vs ELU26 isdn

[rightsaidfred]

Hi All,

What are basic differences between a dual access isdn and a normal elu26 isdn extension?
What is bandwidth in case of dual: 64K?
How to program a dual access?

Thanks.

Hi,

ELU-26 4 INDs - 4 Wire to S0 line jack.
ELU 28 16 INDs - 2 Wire to Line Jack.

Dual access ELU-28's require 32 time slots and that can be some work to achieve in an existing system.

Dual access requires a main supply

Note: ELU28/3 must have access to 32 time slots, when used as DUAL ACCESS.

Initiate Dual Access…
KSEXIIR=1000,CAT=1,EQU=1-1-10-00,ITYPE=20,ACCTYP=1;
ITNUIIR=1001,EQU=1-1-10-00,CAT=5;

Thank you very much.
And does dual access support 128kbps?

Hi

Yes, but in that case, the DTS that might be connected so the SoDASL is not usable as no more channel is available to establish a call.
