SPAN_CONFIG Parameters

The following parameters in Table 7-20 are for the SPAN_CONFIG

command.

Table 7-20: SPAN_CONFIG Command Parameters

Parameter Values

<span> A or B

<span type> 0 = E1_1 (HDB3, CRC–4)

1 = E1_2 (HDB3)

2 = E1_3 (HDB3, CRC–4, TS16)

3 = E1_4 (HDB3, TS16)

4 = T1_1 (AMI, DS1 AT&T D4, Ext ZCS, 3 to 1 packing, Group 0 unusable)

5 = T1_2 (B8ZS, DS1 AT&T ESF 4 to 1 packing, 64K link)

6 = J1_1 (B8ZS, J1 AT&T ESF, Japan CRC6, 4 to 1 packing)

7 = J1_2 (B8ZS, J1 AT&T ESF, US CRC6, 4 to 1 packing)

8 = T1_3 (AMI, DS1vAT&T D4, Int ZCS, 3 to 1 packing, Group 0 unusable)

<span

0 = T1_6 (T1,J1: long haul, same as choice 10)

1 = T1_4 (T1,J1:393–524 feet)

2 = T1_2 (T1,J1:131–262 feet)

3 = E1_75 (E1:120 Ohm / 75 Ohm coax)

4 = T1_1 (T1,J1:0–131 feet)

5 = T1_5 (T1,J1:524–655 feet)

6 = T1_3 (T1,J1:262–393 feet)

7 = E1_120 (E1:120 Ohm)

8 = T1 (T1,J1: long haul pulse 0 dB, gain 36 dB)

9 = T1 (T1,J1: long haul pulse –7.5 dB, gain 36 dB)

10 = T1 (T1,J1: long haul pulse –15 dB, gain 36 dB)

11 = T1 (T1,J1: long haul pulse –22 dB, gain 36 dB)

12 = T1 (T1,J1: long haul pulse 0 dB, gain 26 dB)

13 = T1 (T1,J1: long haul pulse –7.5 dB, gain 26 dB)

14 = T1 (T1,J1: long haul pulse –15 dB, gain 26 dB)

15 = T1 (T1,J1: long haul pulse –22 dB, gain 26 dB)

16 = E1 (Long haul: 120 Ohm)

17 = E1 (Long haul: 120 Ohm / 75 Ohm coax)
