Emergency Call Service
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 mismatch 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:
1. Layer 2 VLAN ID (IEEE 802.1Q-2003)
2. Layer 2 priority value (IEEE 802.1D-2004)
3. Layer 3 Diffserv code point (DSCP) value (IETF RFC 2474)
This network policy is potentially advertised and associated with multiple sets of application types supported on a given port. The
application types specifically addressed are:
1. Voice
2. Guest Voice
3. Softphone Voice
4. Video Conferencing
5. Streaming Video
6. Control / Signaling (conditionally support a separate network policy for the media types above)
A large network may support multiple VoIP policies across the entire organization, and different policies per application type.
LLDP-MED allows multiple policies to be advertised per port, each corresponding to a different application type. Different ports on
