Planning Form Instructions

On Form 2c, System Numbering: Line/Trunk Jacks:

1.For all trunks listed as “PRI” in the Jack Type column:

NOTE:

You cannot use Channel 24 for services.

a.Write the kind of service to be connected to each channel in the Incoming Line/Trunk Type column. If the PRI channel is being used in a private network, write NTWK and the switch identifier in this column.

b.Write unequipped in the Incoming Line/Trunk Type column for any channel not used at this time.

2.For all trunks listed as T1-Tie that do not show an unequipped entry in the Incoming Line/Trunk Type column, write the kind of service connected to each channel in the Incoming Line/Trunk Type column.

NOTE:

If you use common-channel signaling, you cannot use Channel 24 and program the module for tie-trunk emulation.

3.Do one of the following:

a.To select settings for T1 and T1 Switched 56, continue to the next section, “T1 Service.” For T1 Switched 56 service, you must also complete the “T1 Switched 56” section.

b.To select settings for PRI, skip to “PRI Service.”

T1 Service

3

T1 service allows the emulation of different analog lines. You can also order services, such as Megacom 800, over the channels. The capacity, however, is limited to voice calls and data calls using a modem. In addition, beginning with Release 4.0 of the MERLIN LEGEND Communications System, T1 supports ACCUNET Switched Digital Service (or other circuit-switched data service) at

56-kbps when the T1 channel or T1-Tie trunk is configured as T1 Switched 56. Release 6.0 and later systems allow T1 service to provide PRI or T1 Tie service in a private network.

The planning form instructions below apply to both T1 and T1 Switched 56 service except where noted. If you are configuring channels for T1 Switched 56 service, complete these instructions then proceed to the “T1 Switched 56 – Network” section that immediately follows. If configuring T1-Tie trunks for T1 Switched 56 service, proceed to the “Tie Trunks” section after completing these instructions. If you are planning to use T1 service as PRI trunks in a private network, check the PRI box under Type of Service on Form 3b (page 1) and proceed to the “PRI Service” section. See the Network Reference for more information regarding configuration for use in a private network.
