Figure 61 shows three PathBuilder S700s connected through a carrier ATM
network or a private switch. The ATM switch or network should be configured
with Permanent Virtual Circuits (PVCs) connecting one LAN or DS1 port on one
PathBuilder S700 to another port on another PathBuilder S700.

ATM Bridging
Note that the numbers given for these circuits by the carrier are local to one
PathBuilder S700 and have no global significance. For example, VCC number
0/100 is used on two different PathBuilder S700s to mean two different circuits.
The carrier will assign each PathBuilder S700 at each location any number of
circuits to connect each PathBuilder S700 Ethernet port to any other PathBuilder
S700 Ethernet port desired.
The connections in the carrier network are shown for illustration only. Figure 61
shows an example for an ATM switch configuration. Note that the VCC numbers
get translated by the ATM switch since they have local meaning only for every
switch port. For example, the carrier would provide the PathBuilder S700 at the #1
location, four VCCs for the forward and reverse path to connect respectively to
LAN2 and LAN3. VCCs are unidirectional; therefore, two VCCs are designated on
a port of an PathBuilder S700 to transmit to, and receive from, another location.
The PVCs are provisioned by the carrier for use on each PathBuilder S700. These
PVCs are entered in circuit tables within each PathBuilder S700. After these circuits
are built the bridge can use this information to send ATM cells to remote sites.
The PathBuilder S700 supports a maximum of 256 VCs per IMA group, 4000 VCs
for the whole shelf. You first configure each PathBuilder S700 with the PVC
information using menus that prompt you to input specific information about
each Permanent Virtual Circuit. See “Configuring Virtual Circuits” in Chapter 5,
for details.
These PVCs are tied to specific PathBuilder S700 ports (Ethernet slot 4, port 1).
You can associate several PVCs associated to one PathBuilder S700 port. Each PVC
represents the logical circuit being used to connect one PathBuilder S700 port to a
remote PathBuilder S700 port.
