Value Description
Link
Name Any String Link1 Name to identify the SS7 Link. By default the GUI will select a unique
name.
However it is sometimes useful to specify a SS7 Link name that
relates to the remote destination.
Span This is readonly information field. Provides the user with span
number information.
Line
Media
Type This is readonly information field. Provide the user with T1/E1 link
type that has previously been configured.
Signaling
Channel
Single Digit 1-31 User must specify the DS0 location of the SS7 signaling channel. The
timeslot number relates to physical DS0 channel.
Valid options are
E1: 1 to 31
T1: 1 to 24
A usual location of a SS7 signaling channel is 1 or 16.
Error
Type Basic
PCR Basic MTP2 error correction type
Two forms of error correction are defined for an SS7 signaling link at
MTP2: the basic method and the PCR method.
Default: Basic
The basic method is generally applied to configurations in which the
one-way propagation delay is less than 40 ms,
Optional: PCR
PCR is applied on intercontinental signaling links in which the one-
way propagation delay is greater than 40 ms and on all signaling links
established via satellite.
The maximum supported signaling link loop (round trip) delay is 670
ms (the time between the sending of a message signal unit [MSU] and
the reception of the acknowledgment for this MSU in undisturbed
operation).
