# [mode=SDH|SONET] [clock=Ext|Int]
#
# The ’card’ and ’connector’ specification are mandatory.
#
# The card should be identified by a hexidecimal digit representing
# the slot number of the card in the GigaRouter chassis.
#
# The connector should be either ’top’ or ’bottom’.
#
# The ’protocol’ parameter defines the signalling protocol to be used
# in the setup of Switched Virtual Circuits (SVC’s) on this physical
# interface. This parameter is optional. If left unspecified, the
# ATM card uses UNI3.0 signalling by default.
#
# Valid values for the signalling parameter include:
#
# UNI3.0 - for the UNI 3.0 signalling protocol.
#
# UNI3.1 - for the UNI 3.1 signalling protocol.
#
# NONE - for no signalling protocol.
#
# The ’mode’ specification is optional. It can be either SDH or SONET.
# By default, it uses SONET.
#
# The ’clock’ specification is also optional. It can be either Ext(ernal)
# or Int(ernal). The default setting is Internal clocking.
#
#Signalling card=9 connector=top protocol=UNI3.1
#Signalling card=9 connector=bottom protocol=NONE
#Signalling card=a connector=top protocol=UNI3.1
#Signalling card=a connector=bottom protocol=NONE
#
# Interfaces
#
# Lines beginning with the keyword "Interface" define
# GigaRouter logical ATM interfaces.
#
# The format of a logical interface definition is:
#
# Interface ifname [service=service_name] [traffic_shape=shape_name] \
# [bridge_method=method[,restriction]]
#
# The optional ’service’ parameter allows an ATM service to be
# be defined for this logical interface (the ’service_name’ must be
# a name defined in the Services section above).
#
# The optional ’traffic_shape’ parameter allows a traffic shape
# to be defined for this logical interface (the ’shape_name’ must be
# a named defined as a Traffic_Shape above).
#
# If no traffic shape is specified, a default shape of 155Kbps, high
# quality of service is used.
#
# The optional ’bridge_method’ parameter allows an interface to be used
# for RFC 1483 bridging. The valid values for the bridge_method parameter
# are:
#
# llc_encapsulated - Use a single PVC, with each frame
# encapsulated with an LLC header to identify
