CDQPrima USERS GUIDE

6-176-17

Independent Mono (Ind. Mono). For normal operation with G.722, select

1 Ln, and for use when connecting to two different far-end encoders,

use Ind. Mono. If single line is selected, you must enter which line you

will be framing (connecting) to. If independent mono is selected, you

must enter which lines to use for the left and right channels.

When using any MPEG Layer II algorithm, Single Line (1 LN), Dual

Line (CCS 2 LN) and H.221 multi-line (H221 6 LN) modes are available.

The Single Line mode supports all allowed bit rates only when using a

non-terminal adapter type digital interface, otherwise, only 56 and 64

kb/s is supported. The Dual Line mode supports only 112 and 128

kb/s bit rates. H.221 line format allows connecting up to six ISDN lines.

To use BONDING to combine up to six ISDN lines into a larger pipe,

select (H221 6 LN) and enter the lines to use.

MPEG Layer III supports Single Line and Dual Line modes, with the

same restrictions as MPEG Layer II.

Select the line format at the Line Fmt prompt

or use the DLI command from a terminal.

6.1.4.3 Decoder Bit Rate

Under most circumstances, the combination of encoder bit rate, decoder

algorithm and line format will determine the allowable decoder bit

rate. The decoder bit rate must be a multiple of the base rate chosen for

the encoder. For example, if the encoder bit rate is 112 kb/s, the

decoder bit rate cannot be 64 or 128 kb/s because different base rates

(56 vs. 64 kb/s) are used.

Select the appropriate bit rate at the Bit Rate prompt

or use the DBR command from a terminal.

6.1.4.4 Decoder Algorithm

The decoder algorithm is selected at the Algorithm prompt

or using the DAL command from a terminal. The decoder algorithm

can be different from the encoder algorithm only in the decoder

independent YES mode.
