3.3.3 PRIB (Primary Rate Interface Board)
There are two kinds of PRIB according to CPU, but they have the same functions.
The Primary Rate Interface Board (PRIB) provides one (1) PRI interface, or one (1) E1R2 interface; this interface
supports 30 PCM bearer and 2 signaling channels for PRI or E1R2. The PRIB is based on the existing interface
described in ITU-T Recommendations G.704, G.703 and G.823.
PRIB can be installed on the universal slot No. 1-6 of any KSU except the slot No. 1 of 1
st
