Notes:
1. The 5304, 5312, and 5324 are considered standard sets (52xx IP devices) when
used in their basic mode. When any HTML applications are enabled on these sets,
they must be considered with the 53xx family of sets in terms of performance and
quantity allowed on a controller.
2. The number of display sets is a subset of the total sets (IP devices) but in the case
of the MXe Expanded or the MXe Server the controller may not be able to support
additional basic sets if the maximum number of display sets is installed. Refer to
the System Engineering Tool to verify performance limits or other limits.
3. See “SIP Phones and use of TLS (SIP-TLS)” on page 44 for additional information.
4. The absolute limit for display sets on servers has been increased to 5000 in MCD
6.0, but the usable quantity will be restricted to less if there are applications placing
monitors on the lines or trunks in the system. For most systems the practical limit
will remain at 3000.
