Hello,

Is there a way to set TMR (Transmission Medium Requirement) value to 3 ( 
3.1 KhZ), to change it from the default value 0 (Speech)?

part of IAM :

Calling Party's Category:
             Category: Ordinary calling subscriber (10)
             [ 0a ]
         Transmission Medium Requirements:
             Speech (0)
             [ 00 ]
         --VARIABLE LENGTH PARMS[1]--
         Called Party Number:
             Nature of address: 3
             NI: 0
             Numbering plan: 1
             Address signals: 898498847#
             [ 07 03 10 98 48 89 48 f7 ]
         --OPTIONAL PARMS--
         Calling Party Number:
             Nature of address: 3
             NI: 0
             Numbering plan: 1
             Presentation: 0
             Screening: 3
             Address signals: 24110767
             [ 0a 06 03 13 42 11 70 76 ]

In this example TMR is set to 0 (Speech).

Thank you!
