I think the correct name for the 4 port channelised E-1 PA is PA-MCX-4TE1.
Note that the 7200 doesn't support SS7, or RPM. This might not be
important to you right now, but it is a strong indication that new dial
features won't necessarily be implemented in the 7200 platform.
(and it costs pretty much the same as the 24 PRI AS5350 that Aaron
suggested)
