Cable Connections - Quasar SmartCell 212 Installation Manual

4.4 Cable Connections

4.4.1 Normal Connection
In normal connection, the 212/112 is used as the NT side and the
PABX as the TE side. The Sync (timing) is delivered from the 212/112
to the PABX over the ISDN cable. The Sync IN/TE port of the 212/112
is not used.
Note: If the PABX will not accept the 212/112 as a sync source, use the
configuration described in paragraph 4.4.3.
Note: ISDN Ready LED will be ON.
4.4.2 Partial TE mode
In this mode, the 212/112 is used as the TE side and the PABX is used
as the NT side of the ISDN connection. The Sync (timing) is delivered
from the PABX to the 212/112 over the same ISDN cable. To enable
this mode, use the QMS S/W to set the 212/112 to partial TE mode
(Layer 1 = TE, Layer 2 = TE, Layer 3 = NT).
Note: Sync IN/TE LED will be ON.
