OR to split off data channels after 0X32 they'll need a Nortel Data Interface (NDI) plus bandwidth allocation key codes}

Users cannot access PRI lines directly through line appearances or line pools (except PRI line pools). All outgoing PRI calls are dialed via intercom using routing codes. When a trunk card is changed to PRI, all existing line appearances for that card are automatically removed.
