CAP_CONNECT is defined in 3GPP TS 29.078 as follows.
=========================================================================
CAP-gsmSSF-gsmSCF-ops-args {itu-t(0) identified-organization(4) etsi(0)
mobileDomain(0) umts-network
(1) modules(3) cap-gsmSSF-gsmSCF-ops-args(101) version4(3)}

DEFINITIONS IMPLICIT TAGS ::= BEGIN
....

ConnectArg  ::= SEQUENCE {    => 0x30 tag
    destinationRoutingAddress [0] DestinationRoutingAddress , => 0xa0 tag
    alertingPattern           [1] AlertingPattern    OPTIONAL,
...
}

DestinationRoutingAddress  ::= SEQUENCE SIZE(1) OF CalledPartyNumber =>IMPLICIT
(no tag)  

CalledPartyNumber  ::= OCTET STRING (SIZE(minCalledPartyNumberLength ..
maxCalledPartyNumberLength)) => 0x04 tag

 minCalledPartyNumberLength                  INTEGER ::=    2
 maxCalledPartyNumberLength                  INTEGER ::=    18

============================================================
And the raw data is 
"30 0c a0 0a 04 08 82 90 10 99 00 00 00 00".

so, I think the above raw data is decoded as follows.

30 => ConnectArg  ::= SEQUENCE ...
0c => length
a0 => destinationRoutingAddress [0] DestinationRoutingAddress 
0a => length
04 => CalledPartyNumber  ::= OCTET STRING ...
08 => length
82 => odd/even and NoA
90 => INN and NPI
10 99... => digits

thanks in advance.
