Table 3-14. General Link Parameters (E1/T1 Ports) (Cont.)
Parameter Possible Values / Remarks
Multiplier (Kbps) The data rate of each DATA time slot.
56, 64
Note: This parameter is only enabled for the main link only.
Line Type
T1:
ESF
(24 frames per multiframe),
D4 (12 frames per multiframe).
E1:
E1
(G732N-2 frames per multiframe), - CCITT Rec. G.704 - Table 4a
E1-CRC (G732NCRC), - CCITT Rec. G.704 - Table 4b
E1-MF - CCITT Rec. G.704 - Table 4a, with TS16 multiframing enabled.
E1-CRC-MF (G732SCRC-16 frames per multiframe),- CCITT Rec. G.704 - Table 4b,
with TS16 multiframing enabled.
Line Code The line coding method used for zero suppression.
Note: This parameter is only applicable for T1.
B7ZS coding, Jammed Bit zero suppression. A pulse is forced in bit 8 of each 8-bit
period of each channel. Therefore, only 7 bits per channel (1.344 Mbps) is available for
data.
B8ZS
coding, a specified pattern of normal bits and bipolar variations replaces a
sequence of 8 zero bits. This option provides clear channel capability.
Trans - Transparent (AMI) coding, no zero suppression is present.
Sync Defines time required for the link to return to normal operation after a red alarm event
(local loss of synchronization) has terminated
FAST
(after one second),
AT&T 62411 (after ten seconds),
CCITT (after 100 msec)
Tx Gain Mask (db) The selected attenuation value brings your signal level closer to the expected repeater
signal level on the cable.
Note: This parameter is only applicable for T1.
NA
, 7.5, 15, 22.5
Line Length (feet)
Note: This parameter is only applicable for T1.
NA, 0-133
, 134-266, 267-399, 400-533, 534-655
Idle code (Hex) Hexadecimal code transmitted to fill idle (unused) time slots in frames transmitted
through the selected port.
00 - 7C
- FF
Rx Gain The maximum receive sensitivity in dB for the interface.
E1: 12dB, 30dB
T1: 30dB, 36dB
