T1-E1 Trunks
The 1PRIDB-C1 daughter board gives the system T1/E1 trunking ability. This board provides up to
24/30 trunk circuits. In additional to providing digital-quality trunking, the 1PRIDB-C1 daughter board
allows you to have maximum trunking ability with fewer boards. This in turn makes more universal
slots available for other functions.
Conditions
• When adding or removing padding for trunks, use PRG 14-01 for all trunks.
• No Ground Start Trunk Support.
