S 7 IP PHONE PROGRAMMING INTERFACE
ECTION
This section describes how to access the programming interface for IP Phones. The following
describes how to access the User Menu.
1. Using a 8IPLD telephone, press HOLD-Transfer-*-# buttons to enter program mode. The IP User
Menu is displayed.
2. On the IP User Menu, enter the user name and password for the IP Phone. Settings are listed in

S 8 DHCP SERVER CONFIGURATION
ECTION
It is possible to use either an external DHCP server (e.g., Windows Server) or the NEC SL2100
internal DHCP server. With IP Phones, either of these options requires the DHCP server to be
configured to supply the IP terminal options.
If using the internal DHCP server, enable the DHCP server. Refer to
Dynamic IP Addressing, One LAN on page
When using an external DHCP server, you must add a new Option Code to the DHCP scope for the
VoIPDB IP address. The method for adding this service varies depending on the DHCP server used.
S 9 CONFIGURING QUALITY OF SERVICE
ECTION
NEC recommends configuring Quality of Service (QoS) to ensure that the speech quality is not
affected by other data on the network. QoS is discussed further in
page 6-1.
The NEC SL2100 system supports:
• IEEE802.1q (VLAN Tagging)
• IEEE802.1p (Priority)
With the VLAN tagging mode, the NEC SL2100 system can handle packets with or without a VLAN
tag. If the VLAN ID of a packet is different from the registered one, that packet is dropped.
9.1 Layer 2 Priority Control
Layer 2 priority control can be enabled on an Ethernet switch, if it supports VLAN tagging. This allows
layer 2 prioritization.
Using a switch that supports 802.1p allows:
• priority control
• reduction of unnecessary packets (e.g., broadcast packets) and provides circuitry by restricting a
broadcast domain
