ATM/T1 Configuration
For an ATM/T1 configuration, the items shown in Exhibit 3 are identical to Ethernet with the
exception of the traffic path, which must show “atm” for this type of configuration.

When ATM is selected for the WAN interface using the traffic mode parameter, an additional set
of parameters is required (Exhibit 6). First of all, another IP address must be identified for the
ATM interface. The ATM IP address cannot be the same as the Ethernet IP address. In this case,
the Ethernet IP address is only used for debug purposes and is a non-routed interface. This means
that the BTS can only reach other computers directly connected to the Ethernet port of the BTS.
The only routed interface available is through the ATM port. This routed interface address is
specified with the “ip on atm” line item and the corresponding netmask parameter (Exhibit 4).
The information on network address specifications from the Ethernet Configuration section of
this chapter applies to ATM as well. For ATM, the only gateway allowed for the BTS is on the
ATM interface, as specified here.

For an ATM system, the BTS must have some additional configuration for the Management
Private Virtual Channel (Management PVC). Recall the boot parameter philosophy discussed
before. The boot parameters only identify those settings required to allow the BTS to reach the
EMS. Note that the boot parameters only allow specification for one PVC (the Management
PVC), which is used to reach the EMS.
All user traffic PVC parameters are specified in the EMS configuration. Ensure that the EMS
parameters for the Management PVC match those being set here through the boot prompt. If not,
as soon as connection is made with the EMS, the Management PVC will be reconfigured and can
potentially disconnect the BTS from the network.
