Checking system capacity
Checking system capacity
1. Check that the system does not exceed the DECT
system capacity: that is, no more
than 512 handsets or 128 basestations for the system with no more than sixty-four
12-channel basestations.
2. Check that there is no cell limit for a DECT system. The limit is the total count of the
basestations.
3. Check that the limits on basestations and handsets are independent of each other.
Increasing the handset count does not decrease the number of basestations
available to install.
4. If more than 128 basestations are deployed, it is necessary to replan the site with
multiple systems. See the Detailed Site Planning section.
5. Ensure that the location of the controller is not more than 1500 m (wiring length for
Category 5 UTP) from all 6-channel basestations or 1000 m from 12-channel
basestations (unless external power is used). If the location is farther than the
allowed distance, the customer must examine other installation and equipment
configurations with the sales representative and Avaya support personnel.
