IPmux-4 Installation and Operation Manual Appendix E Parameters and Screens
E1/T1 Configuration Parameters E-17
Table E-11. E1 Physical Layer Configuration Parameters (Cont.)
Key Parameter Possible Values Remarks
6 Idle Code
00 – FF
The idle code inserted into unused time slots
by IPmux-4-E1 at the transmit path towards E1
equipment
Default value: 7E
Note: This field will not appear if “unframed” is
selected in the Line Type field.
7 Signaling Mode
CAS Enable
CAS Disable
The E1 framer is set to CAS MF mode and the
operation mode to fractional with CAS mode
CAS MF will not be set in the E1 framer and
the operation mode will be configured to
fractional mode.
Default value: CAS Enable
Note: This field will not appear if “unframed” is
selected in the Line Type field.
8 Cond. Data Pattern
00 – FF
The byte code applied to time slots when fault
conditions occur.
Conditioning pattern can be applied to time
slots toward the IP path when loss of signal,
loss of frame or AIS detected at the E1 line.
Conditioning pattern can also be applied to
time slots toward the E1 line when packets
receive buffer overrun or under-run occurs. In
Unframed mode, conditioning state will result
in AIS transmission. This will be applied when
a LOS is detected at E1 line, or when packet
receive buffer overrun or under run occurs.
Default Value: FF
Note: This field will not appear if “unframed” is
selected in the Channel Type field.
9 Cond CAS (ABCD) Pattern
1 – F
The 4 bit code applied to ABCD bits when
fault conditions occur.
The ABCD conditioning pattern can be
applied toward the IP path when loss of signal,
loss of frame, or AIS is detected at the E1 line.
Conditioning pattern can also be applied
toward the E1 line when packet receive buffer
overrun or underrun occur.
Default Value: 1
Note: This field will not appear if “unframed” is
selected in the Channel Type field.
