[nsp] Channelized DS3

There is the NM-1T3/E3, but it's very restrictive in what 36xx platforms it
can go in:
Cisco 265x XM 
Cisco 2691 
Cisco 3660 
Cisco 3725 
Cisco 3745 

However, it's disqualified for this - it doesn't support channelized T3,
only clear-channel.

HSSI is only a single channel.  A channelized T3 is a bundle of 28 T1
interfaces.  The goal would be for the router to see  the DS3 circuit as 28
separate serial interfaces coming in on one DS3. I could have sworn my Cisco
rep mentioned a 3600 series NM for that purpose once, but I could be
mistaken.  I can pull up the e-mail he sent me when I get into the office
later today.
