Capacity; Voice Gateway Media Card Dsp Capacity - Avaya 1000 Installation And Commissioning Manual

Capacity

Each Communication Server 1000 Main Office (SA or HA) can support up to 1000 branch offices,
consisting of combinations of SRGs, MG 1000Bs, SIP Media Gateways, and Geographically
Redundant Survivable Media Gateways (GR-SMG). The SRGs, MG 1000Bs, SIP Media Gateways,
and GR-SMGs can be deployed in various combinations but the total cannot exceed 1000. The
following limitations apply to the deployed combinations:
• There can be a maximum of 255 SRGs
• There can be a maximum of 1000 MG 1000Bs
• There can be a maximum of 1000 SIP Media Gateways, of which 511 can be survivable with
N-Way database replication
• There can be a maximum of 50 GR-SMGs
Note:
If there are 50 GR-SMGs there can only be 461 Survivable SIP Media Gateways (this allows for
511 end points with N-Way database replication).
Each Branch Office supports up to 400 IP Phone and SIP Line users. Branch Office also supports
up to 128 Time Division Multiplexing (TDM) telephone users. However, since all IP Phones register
with the Main Office, the governing factor is the maximum number of IP Phones that can be
supported at the main office. This means the total number of IP Phones in all offices can be no
greater than the capacity of the main office, as determined using Avaya Communication Server
1000E Planning and Engineering, NN43041-220.
You can use a Co-res CS and SS system as a Main Office, but in a limited capacity (Avaya
recommends no more than 5 branches). The Co-res CS and SS system is limited to 1000 IP phones
(UNIStim and SIP Line) and only 400 Virtual Trunks. The Co-resident Call Server is also limited to
processing 10 000 calls per hour. These numbers directly affect the number of branches supported.
The configuration of an MG 1000B platform depends on:
• the number of line and trunk cards being provisioned
• the number of Voice Gateway Media Cards required to provide a sufficient number of DSP
channels

Voice Gateway Media Card DSP capacity

The Media Gateway Controller (MGC) card can provide up to 256 DSP ports. The Common
Processor Media Gateway (CP MG) card can provide 32 or 128 DSP ports. You can also add MC32
or MC 32S Voice Gateway Media Cards to increase the total number of DSP ports available.
For more information about DSP port provisioning for MG 1000B, see Avaya Communication Server
1000E Planning and Engineering, NN43041-220. When the MG 1000B is running in local mode
(connection to Main Office is down), you need to have enough DSPs to support all IP to TDM
connections (IP Phone to TDM trunk, IP Phone to TDM telephones). For example, use one DSP for
each trunk port and a cumulus of 32 DSPs to support local conference and connections to local
TDM sets.
