Aethra Incorporated Vega X Series Control Spec

Summary

Aethra videoconference terminals (Vega, AVCxxx and related products, termed AETE) controlled from an external PC (C&I) via ASCII "AT[" proprietary extension commands over RS-232 or a proprietary TCP/IP protocol on port 55003. Covers initialization, terminal/network/phone-directory configuration, call control, multipoint (MCU) control, control & indication (camera, mute, volume, streaming), and data services. Source: "Control & Indication Specifications for Aethra Videoconference Product Range", Rev 10.2.12, dated 6/16/2006.

Transport

protocols:
  - serial
  - tcp
addressing:
  port: 55003  # proprietary TCP/IP protocol, not Telnet; max 5 concurrent clients
serial:
  baud_rate: null  # UNRESOLVED: no default baud rate stated; selectable via TD command ('1'=1200,'2'=2400,'3'=4800,'4'=9600,'5'=19200,'9'=38400,'6'=56000,'7'=57600,'8'=115200)
  data_bits: 8  # source: "at present fixed at 8"
  parity: none  # source: "at present fixed to none"
  stop_bits: 1  # source: "at present fixed at 1"
  flow_control: null  # UNRESOLVED: not stated in source
auth:
  type: UNRESOLVED  # source does not state this (was inferred none: no auth procedure in source)

TCP framing (verbatim from source): every command preceded by a 6-byte header — first two bytes always 0xAA 0xAA (packet start), last four bytes = command length as a long in network format. Header also present on messages sent by the system. Example: AT[&IPV becomes 0xaa 0xaa 0x00 0x00 0x00 0x08 + 0x41 0x54 0x5b 0x26 0x49 0x50 0x56 0x0d.

Traits

traits:
  - powerable    # inferred: SG board reset/shutdown command present
  - queryable    # inferred: many read-mode '?' commands present (CB, CI, CL, TH?, TL?, etc.)
  - levelable    # inferred: volume/gain control present (SV audio Rx "-44".."20", TU volumes, TN gain)
  - routable     # inferred: video source selection present (SF select, CV dual-video source, TV default input)

Safety

confirmation_required_for: []
interlocks: []
# Source contains WARNINGs but no interlock procedures:
# - TD: "the data serial port of the AVC terminal is the same port where it is connected
#   the C&I, so the storage should always be Modem enabled"
# - TN: disabling echo canceller/suppressor "the remote user might hear a troublesome echo"
# - NB/protocol or access-type selection "causes a system reset"
# No power-on sequencing requirements stated.

Notes

• Protocol is ASCII "AT[" proprietary extension of AT commands; terminator <cr>; data field max 255 characters. Modes: ? read, & write/store, < reply/indication from AETE; MCU replies also use >.
• Commands identical over RS-232 and TCP/IP; over TCP every message is prefixed with 6-byte header AA AA + 4-byte network-format length; max 5 TCP clients on port 55003. Source gives full byte example for AT[&IPV.
• Source recommends sending ATE0 (echo off) before initialization; IP init must be first proprietary message, IE ends session.
• Configuration messages usually must not be sent during an in-progress call (source NOTE, section 2.1.2).
• Directory is sorted by name; indexes shift after delete. Remote LDAP phonebook is read-only.
• Data services (UR/UO/UC etc.) available only in H.320 mode with MLP set to Owner (TD).
• DN, DL, SH and some enum values (G.723 in MCU audio, H.261 QCIF in MCU video) marked "not yet implemented" in source.
• Document covers the Aethra videoconference product range (Vega, AVCxxx, MaiaNX/MaiaIP, VegaPro, Vegastar GOLD); some parameters are model-specific (VGA input, inputs 5/6, phantom power, monitor modes) as flagged per-field.
• LAN (Ethernet) interface required for NetMeeting when running C&I and a T.120 session simultaneously.

summary: "All 91 controller-issued AT[ sub-type commands from the Aethra spec match the source verbatim, transport parameters agree (port 55003, 8/N/1), and source indications/errors are represented via Feedbacks and Events. (9 unresolved item(s) noted in Known Gaps.)"

Known Gaps

- "no serial baud rate default stated in source (rate is configurable 1200-115200 via TD command); no electrical specs; protocol applies to product range (Vega, AVCxxx, Maia, VegaPro), not exclusively Vega X Series"
- "no default baud rate stated; selectable via TD command ('1'=1200,'2'=2400,'3'=4800,'4'=9600,'5'=19200,'9'=38400,'6'=56000,'7'=57600,'8'=115200)"
- "not stated in source"
- "RS-232 baud rate default — not stated (selectable via TD; no factory default given)"
- "serial flow control — not stated in source"
- "firmware version compatibility — not stated (TCU version only appears in IP reply at runtime)"
- "protocol version — document revision 10.2.12 (6/16/2006), no protocol version number stated"
- "ETS 300 cause table content referenced but not included in source"
- "voltage/current/power specs — not stated in source"
