Configure the Meridian 1 ITG/ISL trunk data 483
Procedure 84
Removing the ITG Trunk1.0 configuration data from Meridian 1
Step Action
1Out existing ITG basic trunks that are being upgraded to ITG ISL
trunks:
a. IdentifyTNs of trunks that are to be outed. Look in TM 3.1 ITG
ISDN IP Trunksapplication for ITG trunks or, in LD 21, request
an LTNof existing basic ITG TIE trunk route. The LTN gives a
list of every single unit. Observe if there are 8 or 4 TNs on the
same card. Note which units are on each card and which is the
starting unit. Count the number of units on each card. If using
the G.729 codec, there might only be four units on the card.
b. LoadLD14 and out the cards one at a time. Enter OUT x, where
x is the number of units on each card and TN = y,where y is the
lowest unit on the card. Give the starting unit on the card.
c. Whenall the trunks on the LTN of the basic ITG trunk TIE route
have been outed, then out the Route Data Block.
2Out the Route Data Block for ITG basic trunks. Use LD 16. REQ =
OUT.When prompted for the customer number and route number,
press Enter. The Route Data Block is then deleted.
—End—
Configure the Meridian 1 ITG/ISL trunk data

Upgrade considerations

If leaving the ITG 8-port trunk cards in the same card slots, use the same
card TNs and route number when building the new ITG/ISL TrunkRoute.
Tore-use the same ESN route list blocks and the ESN translation tables,
then use the same route number when building the new ITG ISL TIE route
and the RLB entries will still be correct.
Remember to make certain changes to the RLB entry in LD 86. For the
ITG/ISL TIE TrunkRoute, configure SBOC = RRA to enable Fallback routing
to circuit-switched trunks.
In ITG Trunk2.0, the digit manipulation tables are not required to reinser t
AC1 or AC2. Therefore, change the DMIs accordingly.
Verifycustomer data block (see "LD 15 Configure ISDN featurein Customer
Data Block" (page 222)). See "LD 17 Configure the ISL D-channel for the
DCHIP card (Large Systems)" (page 218) or "LD 17 Configure the ISL
D-channel for the DCHIP card (Small Systems)" (page 220), as appropriate.
