Notes:
1.
The number of conference, voice mail, and compression
resources is fixed by the purchased option and the number of
DSP devices available; the other values are adjustable.
Compression alters the number of resources available for the
system. For example, by adding 8 compression resources to a
system with 4 DSPs total, the maximum number of three-party
conferences drops to 3 and the maximum number of voice mail
ports drops to 4.
2. The controller supports the G.711 and G.729a audio codecs.
- The G.711 PCM audio codec for 56/64 kbps generally
provides the best voice quality and is comparable to
TDM-type connections.
- The G.729a audio codec for 8/13 kbps provides a good
reduction in bandwidth with only minor loss in voice quality.
- A purchasable MOSS option (Option 120, Number of
Compression Resources) controls the number of G.729a
codecs available to IP devices in the system. Compression
enables more devices to share the available bandwidth. The
option is purchasable in multiples of 8 to a maximum of 16.
The default value is 0. The quantity entered must exactly
match the quantity on the MOSS sheet.
3. A hard drive is strongly recommended for systems that have more
than eight voice mail ports or when Record a Call is frequently used.
4. The base CX/CXi contains an Analog Main Board (AMB) that
supports 4 ONS and 6 LS circuits. By installing an Analog Option
Board (AOB), capacity doubles to 8 ONS and 12 LS circuits. The
AOB does not require extra DSP resources.
