D4 Bank Requirements
The COT D4 bank must be configured with an OIU-2
selected for external timing. The COT bank must be
provided with an external composite clock
synchronized with the network.
SLC-96 Bank Requirements
The COT SLC-96 bank must be configured with a
special service unit (SSU) selected for external timing.
The COT SLC-96 bank must be provided with an
external composite clock synchronized with the
network.
Interface Requirements
The U-BR1TE V unit includes two interfaces. The
loop-side interface is an ISDN U-interface which is
used to deliver Basic Rate service. The carrier-side
interface is a D4/SLC-96 channel bank interface
which is used to insert data into the 1.544 Mbps T1
stream. Only the polarity-insensitive T and R leads
are used in the cross-connection.
Option Switch Settings
Figure 5 displays the locations for SW1, SW3, and
SW6 on the U-BR1TE V. Table 1 contains the option
settings for SW1, SW3, and SW6 of the U-BR1TE V.
