General Notes:
- YES=Compatible.
Zephyr Layer II operation requires Layer III+II firmware and
hardware.
- No=Mode supported by
other codec is not compatible with Zephyr.
- N/S=Not
supported by other codec
- Zephyr
firmware version 2.50 and later supports ISO/MPEG Layer II
at 48kHz sample rate. Firmware version 2.69 and later also
supports ISO/MPEG Layer II Mono at 24kHz..
- Zephyr
supports "CCS CDQ protocol compatible" channel
splitting for ISO/MPEG Layer II stereo and mono 128 modes.
- Zephyr
models 9200, 9201 or 9202 required for stereo and mono-128
modes.
- Zephyr G.722 uses statistical
recovery sync. G.722 sample rate is fixed at 16kHz
regardless of menu setting.
CCS Notes:
- CDQ 1000:
Switch off H.221 (DIP switch 7 , on back, in down position;
to "AUTO" mode) on CDQ to transmit from CDQ to
Zephyr. Terminal adaptor must have "BONDING"
turned off and be set to 64/56Kbps. 24kHz requires MPEG
compatibility.
- CDQ 2000:
Switch to "Decoder independent from encoder"
(Decoder DIP switch #6 in up position;
"INDEPENDENT"). Terminal adaptor must have
"BONDING" turned off and be set to 64/56Kbps.
- CDQPrima: Must be set to front panel option "DECODER/GENERAL/INDEP=YES"
OR Serial port command "DIN YES". To transmit
G.722, sample rate must be set to 16kHz. Primas with serial
numbers beginning with "2" have Layer III. Zephyr
firmware version 2.69 and later may be required to
communicate in certain Layer III modes or dropouts may
occur.
Comrex Notes:
- DX200:
must have ERROR PROTECTION set to "ON" and IMUX
set to "TELOS/CCS" or "CCS". Terminal
adaptor must have "BONDING" turned off and be set
to 64/56Kbps.
- Nexus:
must have "H.221" off.
Dialog4 Notes:
- Zephyr
can transmit to DIALOG4 in the modes indicated. For
DIALOG4 to Zephyr compatibility, Zephyr firmware version
2.69 or later must be used, and compatibility mode set
correctly. MUSICTAXI must have "Configuration/ISDN
accept mode" set to "ALL" AND
"Configuration/ISDN mode" set to "RI,"
"DNRI" or "DNR" depending on firmware
version.
Nagra Note:
- Nagra
"SYNC" mode must be set to "SRT".
RE Note:
- * Modes which require greater than 64kbps will
not work. Zephyr can receive Layer II JStereo, Stereo and Dual from RE when
transmitted at 64kbps (single B channel).
