is summarized in
Table 33: TDM and Media Processing Requirements for Example 5: TDM and media
processing usage
.
If more than one PN had been required in a particular site, intrasite calls between
circuit-switched endpoints in that site would have contributed toward media processing usage
because inter-Port Network calls between circuit-switched endpoints traverse an IP network.
Since only one PN is required in each site in this example, the media-processing usage for calls
between circuit-switched endpoints is zero in each site, as indicated in
Table 30: TDM and
Media Processing usages (Erlangs) for Example 5: TDM and media processing usage
on
page 170.
TN2312 IPSI circuit packs
Sizing the TN2312 IP Server Interface (IPSI) circuit packs is a fairly straightforward process.
The number of IPSI circuit packs that are required in the system depends on the total number of
C-LAN sockets that are required, and the number of ISDN D-channels in the system.
Specifically, each IPSI circuit pack supports up to a combined total of 2,480 C-LAN sockets and
ISDN D-channels. This is a system-wide constraint, as opposed to a site-by-site constraint. For
an IP-Connect system, each PN must house exactly one IPSI circuit pack, neglecting duplicated
IPSI circuit packs for enhanced reliability. Therefore, if the C-LAN sockets and the ISDN
D-channels indicate a need for more IPSI circuit packs than the required number of PNs to
support the TDM usage, more PNs are needed (note that placing two active IPSI circuit packs in
a single PN is not permitted). In other words, the number of PNs must be large enough to fulfill
both the TDM and the IPSI requirements.
In a system utilizing a circuit-switched center stage an IPSI circuit pack is not required in each
port network. However, there are restrictions pertaining to how many port networks can be
supported by a single IPSI circuit pack.
If the number of port networks needs to be increased to satisfy the IPSI requirements, then the
TDM and media processing engineering processes must be redone (since an increased
number of port networks implies an increase in inter-port-network traffic). This is an iterative
process.
