CFY1B current limiter
Issue 6 February 2007 219
CFY1B current limiter
The CFY1B current limiter is used only with the S8700-series Media Server.
The CFY1B circuit pack supports the processor port network (PPN) and the MCC1 and SCC1
Media Gateway expansion port networks (EPNs). The CFY1B current limiter connects behind
the Maintenance circuit pack’s slot. The CFY1B provides:
● current-limited accessory 48-VDC,
● emergency transfer logic,
● current-limited 5-VDC to trip the main circuit breaker if high temperature is detected, and
● duplicated 48-VDC to fans in an EPN cabinet.

J58890MA-1 Multiapplication Platform for DEFINITY
(MAPD)
The J58890MA-1 is a variation of the MAPD platform that transports ASAI links between a
DEFINITY LAN gateway system and an Ethernet LAN. The J58890MA-1 circuit pack assembly
uses the TN801B MAPD (LAN Gateway Interface). This interface is a circuit pack that is built
from industry-standard PC processors, interfaces, buses, and ISA/PCI expansion boards. The
J58890MA-1 takes up three adjacent slots in the carrier. In a CMC1 Media Gateway the
J58890MA uses only two slots if placed in slot six or seven. There are different lists of the
J58890MA. The number at the end after the dash indicates the list. A list represents a different
hardware configuration of the same circuit pack.
The following descriptions are the capabilities of the different J58890MA lists:
● J58890MA-2 supports CallVisor ASAI and LAN Gateway.
● J58890MA-10 supports IP trunking.
● J58890MA-20 supports CallVisor ASAI, Avaya Computer Telephony, and Basic Call
Management System Reporting Desktop.
● J58890MA-30 supports IP solutions.
