6. SYSTEM CONDITIONS
For providing the Remote PIM System to the NEAX2000 IVS, observe the following conditions:
(1) The main site must be the NEAX2000 IVS. The Small Platform System cannot be the main site. The main
site must be a medium platform (320 ports) or a large platform (512 ports). The small platform (72 ports)
cannot be used.
(2) The Remote PIM can be a PIM N-UB, a PIM Q-UA, or a PIM AB-A.
(3) The Remote PIM can be installed at a maximum of 1312 ft. (399 m) distance from the main site. Using line
extension equipment (repeater, MUX etc.), the distance can be extended.
(4) A maximum of 23 lines/trunks can be accommodated in one Remote PIM.
(5) On the remote site, the line/trunk circuit cards can be used as same as the main site, except the CSI card for
wireless system according to UTAM regulation. However, the application circuit cards cannot be used at the
remote site. When providing the ILC card to the remote site, the ICH card must be installed on the main site.
(6) For the Remote PIM System, the installation procedures for modules, circuit cards and peripheral equipment
are the same as those for the regular NEAX2000 IVS, except the DAIA card and the DAIB card installation
and the BUS cable connection. Refer to the applicable manuals for detailed information.
(7) When the link between the main site and the remote site is lost, the system activates PFT (Power Failure
Transfer) automatically on the remote site, if provided.
(8) The resident system programming cannot be set to the remote site while the main site can be set.
(9) When the LC cards that use an AP card directly (i.e., ILC requires ICH, and 4COTB requires 4RSTC.) If ILC
or COTB are mounted in the Remote PIM, the T1 link between the main and remote sites must be configured
as 64 Kbps with ESF and B8ZS.
(10) In the remote site, if the Remote PIM is a 72-port PIM or a 48-port PIM, when installing a 4-circuit card (LC,
DLC, COT, etc.), assign a phantom DK00 to Level 4 and Level 6 of that LT slot. This assignment will shift
the time slots over enabling the use of additional card slots. (This action is not required if the Remote PIM is
a 64-port PIM.)
