LT01 - LT08 : Line/trunk circuit card mounting slots
• LT00
: No connection to MDF. When NEAXmail AD8 is mounted here, inter-
nal modem leads for AD8 are brought out on pins 25 & 50 of LTC1
cable for connection to single-line station or C.O. trunk.
• LT01 - LT04, LT06, LT08 : All line/trunk circuit cards can be mounted.
• LT05, LT07
: 4-port circuit cards that require cabling may be mounted only when 8-
port cards are not mounted in the slot to the left of them.
AP0 - AP5
: Application circuit card mounting slots
MP
: PN-CP03 mounting slot
BUS
: PN-BS00-B (Slot 08 on PIM0), PN-BS01-B (Slot 09 on PIM1) mounting slot
PWR
: PZ-PW86/PW112 mounting slot
PWR0B
: Connector for termination of ring generator when single-line card(s) are mounted. System
power supply does not supply ringing voltage

When an 8-port card is mounted in Slot 04/06, Slot 05/07 can only be mounted with the following cards:
SPN-AP00
SPN-AP01
SPN-ME00
SPN-SC01
SPN-SC02
SPN-4RSTB
SPN-4RSTB-911
SPN-4RSTC
SPN-CK00
SPN-CC00
PN-M03
SPN-SC03 (CSH)/(ICH)

It is recommended that an APR adapter, which has a built-in ring generator, be used in dual-port mode to
provide interface for single-line devices. APRs provide hookflash and disconnect signaling when 1800
series software or higher is used.
