Model 2977 PE1 PE2 adapter installation

The DialFire RAS PTE Series adapters provide one or two 30B+D PRI interfaces in a package that fits in a sin- gle PCI slot in your server.

Because it uses DSP (digital signal processor) technology, the DialFire RAS adapter supports digital or analog connections on PRI circuits. The adapter supports up to 30 channels on each line.

The position of the PRI connectors is shown in figure 5.

Note Line 1 and Line 2 connectors are present on RAS PE1 and RAS PE2 adapters, but only Line 1 is active on RAS PE1 adapters. A RAS PE1 adapter may be field-upgraded to RAS PE2 by the addition of a daughter card
