4600 Series IP Telephone LAN Administrator's Guide

Contents of the Upgrade Script

The following is a sample upgrade script file:
The filenames 4624_000301.BIN and 4606_000301.BIN used in this sample are
examples only. The names do not match those that are used in production.
IF $MODEL SEQ 4624D01A GOTO BIGSETS
IF $MODEL SEQ 4612D01A GOTO BIGSETS
IF $MODEL SEQ 4606D01A GOTO SMALLSETS
GOTO END
#BIGSETS
SET APPNAME 4624_000301.BIN
GOTO END
#SMALLSETS
SET APPNAME 4606_000301.BIN
#END
The 4612 and 4624 models have more programmable buttons and features than the 4606 model.
There are therefore two application files to match the capabilities of the models.

QoS

The 4600 Series IP Telephones support both IEEE 802.1D/Q and DiffServ, and may in the future
support other, possibly proprietary, procedures for implementing Quality of Service. In addition,
other network-based QoS initiatives such as UDP port selection do not require support by the
telephones, but nonetheless can contribute to improved QoS for the entire network. DEFINITY
Release 9.5 supports the capability to download certain QoS parameters (i.e. 802.1Q, DiffServ
values, and UDP port ranges) to the telephone during Registration. See your Release 9.5
administration material for further information about this capability.

IEEE 802.1D and 802.1Q

IEEE's 802.1Q standard defines a tag that can be added to voice and data packets. Most of the
information associated with this tag deals with Virtual LAN (VLAN) management, but 3 bits are
reserved for identifying packet priority. These 3 bits allow any one of 8 priorities to be assigned to
a specific packet. As defined in the standard, the 8 priorities are, from highest to lowest:
7: Network management traffic
6: Voice traffic with less than 10ms latency
5: Voice traffic with less than 100ms latency
4: "Controlled-load" traffic (mission-critical data applications)
