◆ Emergency Call Service – Emergency Call Service (e.g. 911 and
others), such as defined by TIA or NENA.
ELIN identifier data format is defined to carry the ELIN identifier as
used during emergency call setup to a traditional CAMA or ISDN trunk-
based PSAP. This format consists of a numerical digit string,
corresponding to the ELIN to be used for emergency calling.
◆ Policies – Network Policy Discovery enables the efficient discovery and
diagnosis of mismatched issues with the VLAN configuration, along with
the associated Layer 2 and Layer 3 attributes, which apply for a set of
specific protocol applications on that port. Improper network policy
configurations are a very significant issue in VoIP environments that
frequently result in voice quality degradation or loss of service.
Policies are only intended for use with applications that have specific
“real-time” network policy requirements, such as interactive voice and/
or video services.
The network policy attributes advertised are:
■
Layer 2 VLAN ID (IEEE 802.1Q-2003)
■
Layer 2 priority value (IEEE 802.1D-2004)
■
Layer 3 Diffserv code point (DSCP) value (IETF RFC 2474)
