J58890MA-1
The J58890MA-1 is a variation of the MAPD platform that transports ASAI links between a DEFINITY LAN gateway R2 system and an Ethernet LAN. The J58890MA-1 circuit-pack assembly uses the TN801B MAPD (LAN Gateway Interface), a circuit pack built from industry-standard PC processors, interfaces, buses, and ISA/PCI expansion boards. The unit takes up 3 adjacent slots unless placed in slots 6 and 7 -- then it uses only those two slots (in the CMC). J58890MA-1 supports all releases after R6.3.1. J58890MA-1 List 2 is used to support CallVisor and ASAI, while List 10 supports IP Trunking. Ursa Minor is supported by J58890MA-1 List 20 and IP solutions is supported by J58890MA-1 List 30.
