1.4.3 Preparing the PRI Connection
Danger:
The ISDN connection is regarded as a source of voltage that should be
inaccessible to user contact. Do not tamper with, or open, any public telephone operator
provided equipment or hardware. Any hard-wired connection (other than by a non-
removable, connect-one-time-only plug) must be made by trained engineers.
1.
The Hypermedia Gateway’s PRI connection operates in a point-to-point
configuration. The default setting is NT, that is, the Hypermedia Gateway
assumes that it is connected to a PBX as a Network Terminal. Either leave it or
change it to TE.
2.
Set the Clock Synchronization. The default setting is Slave; that is, the PBX
provides synchronization for the mutual PRI clock (see section
Note:
In most cases, the PBX is also configured as a Synchronization Slave. The Master
on the network is the telephone company which provides the PRI connection to the PBX.
3.
Check the RJ-45 connector that will be used to connect the PRI module to the
PBX or network operator. In most cases it must have the pin layout defined in
Table 2. In other cases it must have the pin layout defined in Table 3.
