Same E1, but a different time slot used for calling on a U1930

Hi there, Community members!

Have a nice day!

This post is about the issue of the same E1, but a different time slot used for calling on a U1930. Please see more details as you read further down this post.

Issue Description

The customer use U1930, PRA trunk. The customer wants to specify the ports for incoming circuits ranging from ports 1-7 to ports 10-20 on the outgoing circuit PRA Trunk.

So, the same E1, but a different time slot used for calling on a U1930.

Solution

Here is an example to control the outgoing call. 

We want the phone to call to PSTN. Go through the time slots 10 - 20 and you can configure as per below.

The first method

Add the office number (if already done, please ignore this step):

config add office selectcode no 0 repeatroute no

config add office no 0 officeselectcode 0

config add predeal index 1 changetype delete changepos 0 changelen 1   -------- config number change ,can ignore                                                                                                                               

config add prefix dn 9 callcategory basic callattribute local cldpredeal yes cldindex 1 officeselectcode 0 clipredeal no uselongcli yes  ---- config prefix, can ignore

config modify cvp type dtu tkcincard 1 direction incoming -------------  so 1 time slot can only receive incoming call.

// (Bound the DTU to the office number, here the DTU in slot 4; in U1930 we use the CVS board, so please bind CVS to the office number. This step you should already finish in LMT, so no need to configure it.)

config modify cvp type dtu tkcincard 10 direction outgoing ------------- so 10 time slot can only send outgoing call.

Also, the customer needs to inform the telecom company that they can only initiate the call to 1-7 time slots.

The second method

config add predeal index 1 changetype delete changepos 0 changelen 1   -------- config number change, can ignore                                                                                                                               

config add prefix dn 9 callcategory basic callattribute local cldpredeal yes cldindex 1 officeselectcode 0 clipredeal no uselongcli yes  ---- config prefix, can ignore

config add office selectcode no 99 repeatroute no // config an unrelated office selectcode

config add office no 99 officeselectcode 99 // config an unrelated office no

config modify cvp type dtu tkcincard 1-7 officeno 99 // bind the non 1-10 time slot to unrelated office no

Also, the customer needs to inform the telecom company that they can only initiate the call to 1-7 time slots.
