About Proxy Signaling
SVC proxy signaling is an optional CBX 500 switch and GX 550 Multiservice WAN
switch feature that enables a single signaling entity to signal on behalf of multiple
endpoints. You can use proxy signaling to allow endsystems that do not understand
ATM signaling to set up SVCs via a proxy signaling agent (PSA). The PSA performs
all signaling functions on behalf of the endsystem, known as the proxy signaling client
(PSC).
Before you can configure the PSA and PSC, use the instructions in
“Configuring CBX or GX Logical Ports,”
to configure the ATM UNI DCE logical
ports.
The following terms are used to define proxy signaling functions:
Proxy signaling agent (PSA) — The network port attached to the signaling entity that
performs signaling for non-signaling entities. In the Lucent implementation, a PSA is
an ATM UNI DCE logical port for which signaling is enabled.
Proxy signaling client (PSC) — The network port attached to the endsystem for
which a PSA performs signaling duties. In the Lucent implementation, a PSC is an
ATM UNI DCE logical port for which signaling is disabled.
You can use proxy signaling to enable high-end ATM equipment to support multiple
physical interfaces that share the same ATM address. This application provides
high-end equipment with the ability to support connections that have an aggregate
bandwidth which exceeds the physical interface line rate. The individual connection(s)
must be at a rate that is less than, or equal to, the line rate.
Proxy signaling enables a “smart device” to signal on behalf of a “dumb” device (see
). It allows high-end devices with multiple Network Interface Cards
(NICs) to use a single signaling channel. In this instance, you use proxy signaling to
allow a single signaling entity (PSA) to signal on behalf of multiple, non-signaling
endsystems (PSC). This application extends the ATM signaling protocol to
endsystems that do not necessarily understand ATM signaling.
