The TN767 will also support ISDN-PRI signalling in a FAS environment. What it will NOT do is ISDN-PRI signalling in an NFAS configuration. The TN767 is OK as an ISDN-EXT in an NFAS arrangement but will only support the D-Channel in a FAS configuration.
Only the TN464GP supports firmware upgrades. FYI: The "P" suffix on all circuit pack types indicates that the card is firmware upgradable.
