Modules
Option Modules (MO)
The E1 interface uses CAS signaling for controlling calls between the PABX and the
PSTN.
HiPath 1190: In the event of a problem occurring with the Master TME1 link (see
"TME1 module display readings" on page 3-32) during an external call, the system
will go into a mute state for 3 seconds while the system clock is synchronized.
When the total number of digital trunks configured for the module plus the number
of external analog lines exceed the maximum capacity of the system, the external
analog lines for the EB 202, EB 206 and EB 210 expansion modules are disabled.
The extensions, however, will continue to work as usual. Lines are disabled in the
order that they are physically installed (1, 2, etc.). This process continues until the
total number equals the required number of trunks. The remaining modules contin-
ue operating as usual.
However, in the case of the EB 200, EB 400 and EB 800 modules, we strongly rec-
ommend that you change their slot to prevent deactivation. These modules become
inoperable if any one of their external line slots is disabled.
