E3 Timing Source—The timing source for the E3 transmit clock: system or
loop. If you set the E3 Timing Source to system at one end of the E3 trunk, you
must set it to loop at the other end.
System—Configures the port interface to use the system reference clock
within the shelf as a reference for transmitting.
Loop—Configures the port interface to use the input port Rx clock as the
timing source; timing is received from the service "loop." Select this option
if the E3 UNI module is used for the network/carrier service termination, in
which case the carrier (the service "loop") typically provides the timing.
Number of VPI for VCC—The number of distinct VPIs that can be used for
VCCs: 1..256. Any VPIs not currently in use by VCCs are available for VPCs.

a Select [2] Virtual Interfaces to open the E3 UNI Virtual Interfaces Configuration
menu. This menu is the same as the MCPU Virtual Interfaces menu, shown
earlier in Figure 84.
b Configure virtual interfaces as described under "Configuring Virtual
Interfaces" earlier in this chapter. You configure virtual interfaces for the E3
UNI card in the same way that you configure virtual interfaces for the MCPU
card.
The PathBuilder S700 supports both a DS1 UNI and an E1 UNI module with IMA
(Inverse Multiplexing for ATM). The configuration procedure is the same for both
modules, but different parameters are available on the port configuration menu,
as described under "Configuring DS1/E1 UNI Ports" below.
Configuring a DS1/E1 UNI module involves the following tasks:
Configuring the individual DS1/E1 ports
n
Setting up and configuring IMA and/or UNI groups (if desired)
n
Viewing IMA link and group status

Configuring the DS1/E1 card
