[cisco-voip] 3700 vs 3800 for SRST router

[Fretz, EA Eric @ IS]

3800 series can support PVDM chips directly on the motherboard, which
means the 4 built-in WIC slots can also function as VWIC slots.  On the
3700 series, you have to use a NM-HDV  type of netmodule to get DSPs
into the chassis.  This is important because on the 3845, you only have
to buy the router (w/ voice package) and the VWIC cards.  On the 3745,
you'd have to buy the netmodule cards, as well.  This actually makes the
3845 come out a bit cheaper.  According to this page, the 3700 series is
EOL after Mar 7, 2007:

The 3845 sports a faster main CPU, which will have an impact on the
quantity of MGPC/SCCP devices you can support.
 
Unless you are getting a 3745 used or you already have one, save
yourself the effort and get a 3845.

	Just wondering what the main difference between the 3700 and
3800 series routers are. We're looking for a SRST device that will also
have some T1 trunks and perhaps some analog FXO ports as well. I know
that the different models within each series have different maximum
supported devices, it's likely I'll either get a 3845 or 3745 in order
to get the SRST density I need.
