Capacity
The 5ESS
®
switch supports 2 million busy hour calls (BHC) and up to
128K simultaneous SIP calls, subject to available switch resources on
the IOST, IOSE, and PSTNGW-LT models.
An office supports up to four SIP global switch modules (GSMs).
Configuration
requirements
The SIP for Packet Trunking feature requires that an office be
equipped with a quad link packet switch (QLPS). A 5E-XC
™
that
supports the SIP for Packet Trunking feature must be equipped with a
QLPS, SM-2000 switching modules, OIU-IP, and a PSU2 with DF2
and PHE2 and PH33 protocol handler packs. For information
regarding the PSU2 requirements, refer to “Packet Switch Unit Model
2 (PSU2) Considerations” (4-6).
Note: This QLPS and PH33 are not required for DRM/VCDX.
Constraints
The SIP for Packet Trunking feature is not supported on the following
platforms or configurations:
• Extended Switch Module (EXM),
• Compact Digital Exchange (CDX),
• Non SM-2000,
• Remote Switch Module (RSM), and
• Optically Integrated Remote Switching Module (ORM)
