[nsp] Line coding of PA-MC-STM1 (Cisco 7500)

[Everton da Silva Marques]

Hi,

We have a PA-MC-STM1 card on a 7513 router.

The output reproduced below shows the
PA-MC-STM1 card using NRZ as line coding:

Edge-1#sh controllers sonet 11/0/0
SONET 11/0/0 is up.
Channelized STM-1 SMI PA
  H/W Version : 24.257.2.3, ROM Version : 1.2
  FREEDM version : 2, F/W Version : 1.18.3
  Applique type is Channelized Sonet/SDH
  Description: IP-Channelized [NOC-20G 2-16-1]
  Clock Source is Line, AUG mapping is AU4.

Medium info:
  Type: SDH, Line Coding: NRZ, Line Type: Short SM


How can one change the line coding to HDB3,
assuming that is at all possible?

Thanks,
Everton
