Power Patch Panel

The powered patch panel has two RJ-45 connectors per IP telephone. One port connects to the
switch and the other port connects to the IP telephone. The patch panel contains an integral power
supply, adding power to the spare pairs of the RJ-45.
When the IP telephone is connected to the powered patch panel, the telephone automatically
receives power via the spare pairs on the CAT 5 cable. A local power adapter is not needed.
Power over Ethernet (PoE)

The PoE switch (802.3 AF is only method supported) provides power over the spare pairs. The
switch can be used with other devices than the IP telephones and detects whether or not power is
needed. Using a PoE switch makes it easier to protect the IP telephones from loss of power
(connection of the PoE switch to an UPS).
LLDP
Version 5.0.0.0 IP Phone firmware added support for Link Layer Discover Protocol (LLDP) or IEEE
802.1AB is a vendor neutral Data link layer protocol used by network devices for advertising their
identity, capabilities and interconnections on the IEEE 802 LAN network. LLDP performs functions
similar to several proprietary protocols such as Cisco Discovery Protocol, Extreme Discovery protocol,
Nortel Discovery Protocol (also known as SONMP) and Microsoft's Link Layer Topology Discover
(LLTD). If enabled, the IP terminal takes longer to boot as it waits for an information packet. If no LLDP
information is received within the RX Wait Time, the terminal continues a normal boot process.
This service supports the Link Layer Discovery Protocol (LLDP) standard and is used to transmit and
receive VLAN information ONLY about neighboring network devices and IP Telephones. The following
are a list of VLAN settings which can be received by the terminal during a LLDP session:
LAN port Setting/ VLAN ID

LAN port setting/VLAN Priority

TOS Mode / RTP

TOS mode /SIP

Peer to Peer
An IP telephone can send and receive RTP packets to/from another IP telephone without using the DSP
resources on the PZ-32IPLA/IPLB, PZ-64IPLA/IPLB or PZ-128IPLA/IPLB Daughter Board. This
operation only allows intercom calls between the IP telephones.
If a DT700 IP multiline telephone, or trunk line is required, a DSP resource is needed and a
PZ-32IPLA/IPLB, PZ-64IPLA/IPLB or PZ-128IPLA/IPLB must be installed on the CPU. If, while on a peer
to peer call, a conference call is initiated, the peer to peer connection is released and a new non peer to
peer connection is created using the PZ-32IPLA/IPLB, PZ-64IPLA/IPLB or PZ-128IPLA/IPLB. If the third
party drops out of the conversation, the call reverts to a peer to peer call (silence may be heard while this
conversion is made by the system).
