It is an ISDN route.
SL60 = ISDN.

Hi,

I know it is an ISDN route. But I need to know the type of the Signaling Protocol. (eg DPNSS or CAS R2 )

Thanks.
 
DPNSS and CAS R2 are NOT ISDN protocols.
 
hi if use tlu 76 signaling is pri_net
 
TLU76 can support a number of protcols including DPNSS, CAS, Public ISDN (user or network), Qsig, CAS extension and even C7 depending on the oblique number.
TLU76/1 configured as ISDN can also support user and network configuratons.

Strictly G.703 is an physical interface definition not a protocol but yes TLU76 does comply with G.703.

The clue to the configuration in this case is the RODAPdata. Type SL60 is ISDN and the data in VARO digt 1 indicates "National ISDN" the note for which states -
"A national ISDN protocol is used when connected to a public exchange at the T-reference point.
For the following application systems a national variant of ISDN exists:
Sweden, Australia, Norway, Finland, Austria, The Netherlands, Italy, Spain, Belgium, Ireland,
Singapore, New Zealand, USA, Switzerland, Portugal, France, Great Britain, Germany, South Africa, Mexico and Denmark."

So in this case it is confgured for the user side of a public ISDN connection so I assume the use of TLU76/1 (if it works). The variations to "standard" ISDN signaling will depaend upon the Applicaton System (country) the installion is using.
