Menus Reference Manual: Slot/Channel Set-Up Menu
3 – Start
The Start option specifies the first timeslot or channel number to be used. The remainder of the channels up to the
number selected will be filled sequentialy.
Choices:
if T1: from 1 to 24
if E1: from 1 to 30 if timeslot 16 unavailable, 1 to31 if timeslot 16 available
note: the options displayed for a start number will only be those such that the start number plus number of channels is
less than or equal to the total number of channels on the service (24 for T1, 30 or 31 for E1)
Default:
[1]
4 – Allocation
If the number of channels used is set to half or less than the total channels on the service, this option allows the channels
to be allocatd as a contigous block or as alternating used and unused channels. Your service provider will specify which
they prefer. The most common use of alternate channel allocation is to meet pulse density requirements for a 64 Kbps per
channel link with AMI or inverted AMI encoding.
Default:
[contigous]
note: this option appears only if the number of channels is:
T1 – 12 or less
E1 slot 16 available, odd start number – 16 or less
E1 slot 16 available, even start number – 15 or less
E1 slot 16 unavailable, odd start number – 15 or less
E1 slot 16 unavailable, even start number – 14 or less
If E1 timeslot 16 is toggled from available to unavailable after the maximum number of alternating timeslots has been
set, allocation will automatically revert to contiguous.
4/5 – Speed
The Speed option displays the data rate per channel selected in the T1/E1 set-up menu. This option is display only and
cannot be changed here.
5/6 – E1 Timeslot 16
Some E1 service providers reserve timeslot 16 for line management. If your service specifies that timeslot 16 is for their
use, toggle this option to reserved.
