General Product Description
Note: The MP card at Remote Site has the same system data as the CPU at the Host Site;
the Host Site automatically downloads system data to the Remote Site at the time of
setup. In normal operation, Main Site automatically downloads a copy the system data to
Remote Site through the network once a day.
System Outline
- The MP card at Main Site controls system processing, and Remote Site follows the
Main Site.
- Remote Site can accommodate most terminals and trunks such as Dterm, Single-Line
telephone, PS, DtermIP, COT, ISDN, etc. The Attendant Console, Dterm Attendant
position, and Add-on Module are not supported at the Remote Site.
- Local Switch (TDSW) at Remote Site controls connections within the Remote Site if
possible.
- In the case of connections between Main-Remote and Remote-Remote, the voice path
is connected via Peer-to-Peer or IP-PAD.
- If the communications between Main-Remote are interrupted, the Remote Site
survives by itself after the system reset.
Advantages
- The system regards the terminals accommodated in both Main Site and Remote Site
as
- the extensions in the same office. Therefore, the service transparency is superior to
CCIS.
- Remote PIM over IP has no limitation of distance between Main and Remote.
- Remote Site has a switching function at local. This provides the effective
configuration of C.O. line. In addition, the Remote Site can accommodate AP cards.
This is an advantage to accommodate ISDN lines especially.
- The Remote Site survives by itself even if the link between Main and Remote is
disconnected. Therefore, the impact to users at Remote Site will be smaller if the link
between Main and Remote is disconnected.
- This feature can reduce the bandwidth used on the WAN that is connected to CO lines
at Remote Site, rather than DtermIP at remote location or the Media Converter (MC)
accommodation.
