### Capacities

#### Switch capacity

ASB 150 02 supports a maximum of speech 60 channels.

Speech channels can either be used on request for the normal traffic between an originator and a terminator or they can be permanently assigned to features such as Music on Hold and Background music.

In case of the normal traffic a maximum of 120 individuals can be involved in a:

- Trunk to Trunk connection (Route)
- Trunk to Tieline connection (Network-Node)
- Trunk to S-Terminal connection
- Trunk to Voice over IP gateway connection
- Trunk to Extension connection
  (Fixed, Cordless and IP)
- Extension to Extension connection

as well as in a vice versa connection.

In respect to a duration of 1 hour, this results in a maximum traffic of 48 Erlang at a Grade of Service (GOS) of 1,5%.

#### Trunk capacity

The maximum number of trunks is defined by the following parameters:

- Memory available in the system
  this limits to a theoretical maximum of 120 trunks
- Free slots for boards available in the system
  dependent on the configuration. For detailed information see Capacity Overview.
- Physical capacity on BP128i.
  The maximum amount of RJ45 sockets per cabinet is 72. This is shared between extensions, trunks, basestations, etc.

#### Extension capacity

The maximum number of extensions is defined by the following parameters:

- Memory available in the system, this limits to a theoretical maximum of 300 extension
- Free slots for boards available in the system dependent on the configuration. For detailed information see Capacity Overview.
- Relation between number of extension and number of trunks. This is very much dependent on the customer configuration. E.g. in Hotel installations the number of extensions compared to the number trunks will be much higher, whereas in Call Centers it will be much lower.
- Physical capacity on BP128i.
  The maximum amount of RJ45 sockets per cabinet is 72. This is shared between extensions, trunks, basestations, etc.
