Optical Multiservice Edge 6130 NT6Q92MA Rel 1.0 Iss 1 Standard September 2006
Procedure 8-1 (continued)
Ordering OME6130 chassis, circuit packs, and software
Step Action
9 Determine the number of STM-1o/e services that are required, record the
number in
Line 11 . If no STM-1o/e services are required, enter ‘none’ on Line
11 .
Note: A maximum of 8 STM-1o/e ports can be provisioned per OME6130
shelf (2 ports for each 2x155M tributary circuit pack).
10 Determine the number of 2x155M tributary circuit pack that are required.
Divide the number recorded on
Line 11 by 2 and record the round up integer
value on Line 12 . Enter ‘none’ if no 2x155M tributary circuit pack is required.
11 Add the number of tributary circuit packs recorded on Line 4 , Line 6 , Line 8 ,
Line 10 and Line 12 .
Note: The OME6130 chassis has four tributary slots for services. Up to four
circuit packs can be added to the chassis. Refer to Shelf equipping rules on
page 8-4 for more details.
12 Determine the type of E1/DS1 cables required.
If you need Then
4 tributary circuit packs or less go to step 12
5 tributary circuit packs or more more than one OME6130 shelf needs to
be ordered. Re-assign some of the
services to another OME6130 shelf and
ensure that up to 4 tributary circuit pack
is required per shelf, then go to
step 1
on page 8-23
If you require Then
E1 electrical interfaces
at 75 Ohm Enter ‘75 ohm’ in Line 13 .
E1 electrical interfaces
at 120 Ohm Enter ‘120 ohm’ in Line 13 .
DS1 electrical interfaces
at 100 Ohm Enter ‘100 ohm’ in Line 13 .
no electrical E1/DS1 services Enter ‘none’ in Line 13 .
