4300T User Manual Edgewater Networks, Inc.
Version 1.7 21
Most installations will use a single DLCI for
both voice and data traffic. However, in
instances where the network will provide a
different quality of service based on DLCI
number it is desirable to place all voice traffic
on one DLCI and then configure a second DLCI
for data. In this case, the Secondary DLCI is
configured as follows:
A. Select Network.
B. Select the T1 link next to the radio button to proceed to the T1
Configuration page.
C. Select Enable in the Frame Relay Secondary Settings section of the page.
D. Enter the Secondary DLCI, IP Address, Network Mask and Gateway for
the data traffic using the Secondary DLCI.
Timing
Display and set the clock timing source for the T1/E1 interface. The timing can be
either derived from the network (External) or provided to the T1 interface by the
EdgeMarc (Internal). With a carrier-provided T1, the timing is usually derived from
the network (External, the default setting).
Warning: Mismatched timing modes can result in WAN connectivity but with
intermittent data loss.
Payload Loopback
Display and set the loopback setting. During T1 line testing the local interface can
be set to Loopback to allow the network provider to verify connectivity and line
quality. For normal operation the setting should always be No Loopback (the
default setting).
Configure the DHCP Server
The 4300T can act as a DHCP server granting IP
addresses to PCs, workstations, servers or voice
devices (IP phones, IADs or softphones)
connected to its LAN interfaces. DHCP is a
protocol that enables IP devices to obtain
temporary or permanent IP addresses (out of a
pool) from centrally administered servers.
The user can configure blocks of IP addresses, a
default gateway, DNS servers, NTP server
address, Time offset from NTP value, WINS
address and TFTP/FTP server name that can be
served to the requesting IP devices.
In addition the 4300T will provide its LAN IP
address in DHCP user options 150 and 151 for
