The time schedule is a 24-hour clock which is divided up the same way for
all 7 days. Basic steps to program Time of Day for ITG routes are as follows:
a) Go to LD 86 ESN data block to configure the Time of Day Schedule
(TODS) for the required ITG control periods.
b) Go to LD 86 RLB and apply the TODS on/off toggle for that route list entry
associated with an ITG trunk route.
(3) Use the traditional PSTN for modem traffic
ITG does not support modem traffic except Group 3 fax. You must configure
the Meridian 1 routing controls to route modem traffic over circuit-switched
trunks instead of over ITG.
Use the ESN TGAR, NCOS, and facility restriction levels to keep general
modem traffic off the ITG route.
Configure the IP router on the T-LAN
The ITG node telephony network, or T-LAN must be placed on its own
subnet. The router should have a separate 10/100BaseT interface subnetted
for the T-LAN and should not contain any other traffic. Other IP devices
should not be placed on the T-LAN.
Priority routing for Voice over IP packets
Routers having the capability to turn on priority for voice packets should have
this feature enabled to improve Quality of Service performance. If the Type
of Service (TOS) field or Differentiated Services (DiffServ) is supported on
the IP network, you can configure the decimal value of the DiffServ/TOS
byte. For example, a decimal value of 36 is interpreted in TOS as "Precedence
= Priority" and "Reliability = High".
Do not change the DiffServe/TOS byte from the default value of 0
unless directed by the network administrator to do so.
