GENERAL NOTES:
YES = Compatible with ZephyrExpress.
N/S=Not supported by other codec.
ZephyrExpress supports ISO/MPEG Layer II at 48kHz sampling only.
ZephyrExpress supports “CCS CDQ protocol compatible” channel splitting for ISO/MPEG
Layer II stereo and mono 128 modes.
ZephyrExpress G/722 uses statistical sync. G.722 sample rate is fixed at 16 kHz 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 ZephyrExpress. Terminal adapter must have “BONDING”
turned off and be set to 64/56Kbps. Switch on ISO/MPEG bit stream (DIP switches 6 and 8 on
back, to up position).
CDQ 2000: Switch to “Decoder independent from encoder” (Decoder DIP switch #6 in up
position; “INDEPENDENT”). Terminal adapter must have “BONDING” turned off and be set
to 64/56Kbps.
Prima: 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 16 kHz. Only Primas
with serial numbers beginning with 2 support Layer 3.
COMREX NOTES:
DX200 must have ERROR PROTECTION set to “ON” and IMUX set to “TELOS/CCS” or
“CCS”. Terminal adapter must have “BONDING” turned off and be set to 64/56Kbps.
