think legacy monitoring systems wherein sonet/scada was used and
there is a requirement/desire to replace gear and move towards
converged ip infrastructure. the issue is that some
sensors/interfaces aren’t natively ethernet and require some low-speed
interface to bring it into the ip domain.
however — this falls in line with what you’ve talked about with
low-speed “mix-n-match” flexibility. i think cisco’s market
(initially) was cell-site/ran backhaul. i’ve not done a price/module
comparison between asr1k and asr902/903 — but would assume it comes
down to requirements. both types of kit have been solid (with their
oddities, of course) in my experience.
I've never used the ASR902 or ASR903, so can't speak from experience.
But looking at their density, my guess is they'd occupy much less space
than an ASR1004 or ASR1006, so that would make sense given an ASR1000
packed with tons of low-speed ports won't need that much 1Gbps or 10Gbps
Ethernet uplink real estate to soak up space.
However, I have a feeling IOS XE on the ASR1000 may be more feature-rich
than IOS XE ASR901 (based on some of the feedback those operating the
box have posted in recent months). But, of course, I could be wrong...
