3.3.24 4SLA (Not for U.S.), 8SLA, (for All Countries) and 16SLA (Not for U.S.)

Introduction

The 4SLA, 8SLA, and 16SLA (subscriber line analog) modules connect OfficeCom and OfficePoint (not 16SLA) to analog telephones and supplementary equipment (such as group 3 fax machines and entrance telephone adapters) via analog interfaces.

The 8SLA is supported in the U.S.; the 4SLA and 16SLA are not.

Note: Pinouts shown are at the board itself. The supplied main distribution frame cable (MDF cable) reverses the signal order before the MDF.

Not for U.S.: The 16SLA subscriber line module connects OfficeCom to conventional standard telephones and supplementary equipment (such as group 3 fax machines and entrance telephone adapters) via 16 analog interfaces.
