4 CHANNEL DS3/E3/STS-1 LINE INTERFACE UNIT
PRELIMINARY
REV. P1.0.5
25
Address:
The register addresses are presented in the
Hexa-
decimal
format.
Type:
The Command Registers are either Read-Only (RO)
type of registers or Read/Write (R/W) type of regis-
ters.
The default value for each of the bit-fields within these reg-
isters is "0".
a. Operating in the Hardware Mode.
In order to configure individual Channels into the ap-
propriate mode, set the E3_Ch(n), and the STS-1/
DS3_Ch(n) input pins (where n = 0, 1, 2, or 3) to the
appropriate logic states, as presented below
inTable 3.
b. Operating in the HOST Mode.
To configure a Channel into the appropriate mode,
write the appropriate values into the STS-1/
DS3_Ch(n) and E3_Ch(n) bit-fields within the Com-
mand Register CR4-(n), as illustrated below (refer to
Table 2 for the correct address for each channel).
COMMAND REGISTER, CR4-(N)
Table 4 relates the values of these two bit-fields to the
selected data rates.
