GI/Jerrold headend equipment
Addressable controllers
- AH and AI series: older Jerrold addressable controllers
- Series of machines: AH-1, AH-2, AH-2E, AH-4E, AI-0, AI-0S, AH-8
- PDP-11 based (per ref)
- Minimal information available.
- Discontinued in 1990.
- ACC: Addressable Controller (Addressable Control Computer?)
- ACC-1000:
- Minimal information available
- i8086?
- ACC-2000:
- 20MHz 80486 PC with 52MB hard drive, 3.5 and 5.25in floppy drives, and 4MB RAM.
- SCO Xenix System V operating system
- Includes 8-port port multiplexer, diagnostic modem and Jerrold cable interface.
- Cable interface: 106.5 MHz or 108.5 MHz, selectable
- Supports STARFONE telephone IPPV (STARFONE modems are optional)
- Billing interface (“Wirelink”) has same format as Jerrold AH-4E or AI-O controllers.
- ACC-3000:
- Compaq PL800 (per ref)
- Listed on http://web.archive.org/web/20030225203936/http://broadband.motorola.com/noflash/analog_acc.html, minimal info
- ACC-4000:

- One (ACC-4000 Lite) or three (ACC-4000 Classic and RAID) 2GB hard drives.
- Runs SCO OSE UNIX 3.0, Unify ACCELL 2.5 GUI, and Sybase System 10 database, with ACC-4000 software.
- Three versions: ACC-4000 Lite, ACC-4000 Classic, ACC-4000 RAID
- Lite version supports up to 30,000 set-tops.
- RAID version includes a RAID controller
- Earlier versions:
- ACC-4000/400XP: applicationDEC 400xP (DECpc 400XP?) platform
- ACC-4000/433T: DECpc 433T

Addressable network interface controllers
- ANIC-A: Addressable Network Interface Controller. Connects an ACC-4000 to the biphase data network. Used to control scramblers and other headend equipment.
Scramblers and modulators
- DS/E: Digital Scrambler/Encoder
- An earlier (pre MVP) Jerrold RF-mode scrambler.
- HVP-III (datasheet) (Tocom system)
- Tocom 5500 series encoder
- Tocom 5507 series set-tops (datasheet)
- MVP and MVP-II Modulating Video Processor
- Jerrold baseband video scrambler and modulator.
- Capable of emulating older RF scramblers, e.g. DS/E.
- QVP (datasheet): Quad Video Processor.
- Modular rackmount video processor, essentially four MVPs in a single 1U rackmount unit.
Terminology
- STARfone: Telephone-based IPPV system, where the STB communicates with the headend using a telephone line.
- STARVUE: Also known as “two-way”. RF-based IPPV system, where the STB communicates with the headend using the Cable TV network.
