Coding This is a type of line code which helps to against signal loss during
transmission. You have to configure same coding type in both
connected PRI devices.
Depending on a T1 or E1 line the port is connected to, you have the
following options.
T1: AMI (Alternate Mark Inversion), B8ZS (Binary Eight Zero
Substitution).
E1: AMI (Alternate Mark Inversion), HDB3 (High Density Bipolar of
order 3 code).
Digit Handling Specify the signalling method the X6004 accepts to receive a callee’s
number through a specified PRI port.
En-bloc: The X6004 expects to receive a complete callee’s number at
one time.
Overlap: The X6004 expects to receive digits of a callee’s number one-
by-one.
