Description
The PZ-4LCA and PZ-8LCE daughter boards are mounted on the
CD-4LCA/CD-8LCA. These boards provide:
♦ 4-Port Single Line and 8-Port Single Line analog extension ports
(used for on-premise analog telephones, fax machines, and analog
modems).
The CD-4LCA/CD-8LCA is not rated for OPX use. A CD-4DIOPA
blade should be used instead (it supports the analog DID and single
line telephone interface functions, such as Off-Premise Extensions).
♦ Connector for CD-4LCA and CD-8LCA Blades
♦ Ring Generator
♦ Caller ID Sending Ability
♦ Message Wait Lamping Ability
♦ Constant current type battery feeding (25mA / -28Vdc)
♦ Feeding Polarity Reverse Ability
The CN2 (PZ-4LCA/PZ-8LCE) and CN3 (PZ-8LCE only) connectors each
provide connection to four analog station ports and are not polarity
sensitive. The PZ-8LCE consumes eight ports ranging between ports
001-512 (remember that the CD-8LCA consumes eight ports).
