Signaling Tab
The
Signaling
Tab is used to modify the T1 and E1 bit states for the selected signaling protocol.
These are the A & B bits for D4 (a.k.a. Superframe) and the A, B, C & D bits for ESF and E1
signaling. This gives the TSP the flexibility to match the protocol of the equipment under test if
using a different standard.
Figure 24 Signaling Tab Screen
The first field is for using a predefined protocol and has
*Factory Default
listed. This uses the bits
states as defined by the standard for the Channel Protocol chosen on the
Type
tab. Clicking the
arrow will list equipment that Teltone Corporation has verified the default bits states used during
call progress. All predefined settings provided by Teltone will begin with a “*”. All others listed
without the “*” will be those created by the user.
User Define Field
The
User Define
field is checked if it is necessary to change the bit state parameters to match the
equipment under test. Once checked, it will become grayed out and the predefined protocol field
above will become blank. The
Undo Changes
and
Save As
buttons become available at this point
and the bit state
Outbound
(end initiating call) and
Inbound
(end receiving the call) fields can be
edited. A 1 or 0 can be entered into these fields since signaling is done in a binary form. An X is
used for a Receive Bit when that signaling bit is not used.
Information on the bit states for the equipment being tested by the TSP should be obtained from
the manual, vendor or technical support of that product.
Note:
For T1, when using D4 framing, the bit fields are in ABAB format and the C and D bits must
match the A and B bit fields. This is because D4 does not employ C and D bits and will cause
signaling problems.
