CX II/CXi II Controller
Table 11: Maximum CX II/CXi II configuration
Feature/ Resource Value/Quantity Notes
RTC processor 400 MHz This processor is listed as 450 MHz in the Engineering Tool.
E2T processor N/A The CX II uses a single processor for both RTC and E2T functions.
Memory (RAM) 512 MB Expandable to 1024 MB
IP Users and
Devices (Including
SIP Users)
150 Up to 16 IP devices may be connected directly to the powered Ethernet
ports on the front of the CXi cabinet.
TDM Devices 150 ONS devices only. DNIC devices are not supported on the CX II.
Total Devices 150
ACD users
(active agents)
50 To install the maximum number of ACD users will require the
maximum number of digital trunks and DSP resources.
IP gateway (E2T) 32 (default)
64 (max)
Echo cancellation is done in one DSP for the basic system. Each
T1/E1 combo module provides 32 channels of hardware echo
cancellation.
Conference
channels
30 Each conference may have from three to eight members, but the total
cannot exceed the allowed maximum.
Voice Mail 16 The maximum allowed number of voice mail ports is fixed at 16 in this
controller.
Compression
channels
64 G.729a compression is not a standard offering on base systems.
Additional DSP resources are needed to achieve the values shown.
Compression is added in blocks of 8 bi-directional channels on Quad
DSP and DSP II modules only. (DSP II preferred).
T.38 16
Record-a-Call 8 Every Record-a-Call session uses a conference resource and a voice
mail session from the available pool. The maximum number of
simultaneous sessions supported is 8, but may be limited to less than
this by the available resources.
CIM ports 3 One Quad CIM card can be installed, but only the first 3 ports will be
functional.
ASUs supported 3 Up to 3 external ASU and ASU II cabinets can be installed.
LS trunks (in ASU) 36 Up to 12 on internal AMB/AOB, and 24 in external ASU.
IP networking yes The system can support a maximum of 2000 programmed IP trunks,
but the number which can be used at any one time will be limited by
other resources.
MMC modules
(installed slots)
DSP II (2,3)
T1/E1 Combo
(1,2)
Quad BRI (1,2)
Quad CIM (1,2)
The Dual DSP, Quad DSP, Dual FIM, and the Dual T1/E1 modules are
NOT supported on the CX II.
Digital links 2 T1/E1/PRI,
8 BRI
Digital trunks may be either on embedded Quad BRI (8) or T1/E1
Combo modules (2). Dual T1/E1 module does not have the added
DSP and echo cancellation resources needed for this system.
Peripheral cabinet 0 Does not support a FIM.
NSU/DSU cabinet 0 Does not support a FIM.
