Table 3-5: T1/E1 Span Isolation

Step Action

1 Have the OMCR/CBSC place the BTS OOS.

2 To disable the span lines, locate the connector for the span or spans which must be disabled and

remove the respective connector from the applicable SCCP cage Span I/O board (Figure 3-2).

Configure Optional Channel Service Units

The M-PATH 537 Channel Service Unit (CSU) module provides

in-band SNMP-managed digital service access to T1 and fractional T1

lines. The M-PATH 437 Channel Service Unit (CSU) module provides

in-band SNMP-managed digital service access to E1 and fractional E1

lines. CSU modules plug into the CSU shelf (see Figure 3-3).

The CSU shelf can support two M-PATH 537 or two M-PATH 437 CSU

modules. A 537 CSU module supports a single T1 span connection. A

437 CSU module supports a single E1 span connection.

Remote M-PATH management is available through SNMP over an

in-band data link on the span line (using a facility data link or

8-64 Kbps of a DS0 channel). The unit at the near end of the

management path can be an SNMP manager or another M-PATH CSU.

Programming of the M-PATH is accomplished through the DCE 9-pin

connector on the front panel of the CSU shelf. Manuals and an MS

Windows programming disk are supplied with each unit.

For more information refer to M-PATH T1 Channel Service Unit User’s

Guide, Kentrox part number 65-77538101 or the ADC M-PATH E1

Channel Service Unit User’s Guide, Kentrox part number 1174139.

Setting the Control Port

Whichever control port is chosen, it must first be configured so the

control port switch settings match the communication parameters being

used by the control device. If using the rear-panel DTE control port, set

the SHELF ADDRESS switch SA5 to “up.” If using the rear-panel DCE

control port, position the SHELF ADDRESS switch down.

For more information, refer to the 2-Slot Universal Shelf Installation

Guide, Kentrox part number 65-78070001, the M-PATH T1 Channel
