Model 2977 PT1 PT2 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 6.
Note Line 1 and Line 2 connectors are present on RAS PT1 and RAS PT2
adapters, but only Line 1 is active on RAS PT1 adapters. A RAS PT1
adapter may be field-upgraded to RAS PT2 by the addition of a
daughter card
