[cisco-voip] Maximum number of T1 on 3845

[Lelio Fulgenzi]

http://www.cisco.com/en/US/prod/collateral/routers/ps259/product_data_sheet0900aecd8057f2e0.pdf

i was referred to this by our SE. although the table says the 3845 will support 24 T1/PRI ports, the max simultaneous calls shows about 450 which is just under 20 ports (when dividing by 23, just under 19 when dividing by 24).

hope this helps.

    3845 supports at least 16, more likely 24 pris if I remember right. We chose
    them over 6509e with CMM blades because they provided appropriate density
    and a newer voip platform.

    For one particular client I've got a series of 8 x 3845's with 12 PRI's
    + 230 configured xcoding sessions per device and no cpu/memory issues to
    speak of.  Nominal CPU utilization is around 35% with peaks of about 50%
    during peak call times.
