M-77 MEGACOM800 SERVICE
1. General Description
AT&T’s MEGACOM 800 (INWARD WATS) network can be used.
Note 1:When a call has terminated by the CALL-BY-CALL SERVICE SELECTION [C-105], no indication to
distinguish it from a call termination by other services is made to a terminating terminal.
Note 2:To identify a terminal to which a call has terminated, data must be registered using the “ACDD” com-
mand so that a call-terminating terminal can be identified by a terminating number.
2. Operating Procedure
No manual operation is required.
3. Programming
In addition to the Basic Office Data for ISDN, the following data should be assigned.
STEP 1: ACBC - Select CODE2 (=MEGACOM 800) in this command.

Q-SIG/ISDN INTERNATIONAL GATEWAY SWITCHING
Q-5 Q-SIG/ISDN INTERNATIONAL GATEWAY SWITCHING
1. General Description
This feature allows converting a User Information Layer 1 Protocol (µ-law/A-law) of call originated to ISDN
line according to the office data. See the figure below for examples.
[Case 1: Conversion in tandem office]
(a)Incoming Call from ISDN line (SETUP message is received)
When µ-law is selected as output Layer 1 protocol to outgoing trunk.
When non-conversion is selected to outgoing trunk (the Layer 1 protocol is output as received).
Incoming Call from ACIS/CCIS line (SETUP message is not received)
When A-law is selected as output Layer 1 protocol to outgoing trunk.

2. Operating Procedure
No manual operation is required.
3. Service Conditions
1. This feature is available since Series 7400 Release 9 software.
2. This feature is available for a call to ISDN line (This feature does not support the station-to-station call nor
an outgoing call to CCIS line).
3. Only user information Layer 1 protocol included with Bearer Capability (BC) information element is
converted. Layer 1 protocol included with Low Layer Capability (LLC) and the other information element
are not applied. [Case 2: Conversion in Originating Office]
(a) Outgoing Call from D
term/ATT (SETUP message is not sent)
When A-law is selected as output Layer 1 protocol to an outgoing trunk.
(b) Outgoing Call from ISDN terminal/PS (SETUP message is sent)
When µ-law is selected as output Layer 1 protocol to an outgoing trunk.

Q-SIG/ISDN INTERNATIONAL GATEWAY SWITCHING
4. When the protocol is selected as AUSTRALIA in the route class data (assigned in ARTD, CDN65: INT)
and the coding standard is “00” in BC information element, call in A-law only can be connected (call in µ-
law is disconnected).
5. This feature is activated when SETUP message is sent.
6. This feature is available only when user information Layer 1 protocol is A-law or µ-law (JT-V110/X30 or
JT-X31, etc. cannot be converted).
7. The user information Layer 1 protocol is not added to SETUP message if the received BC information
element does not contain the Layer 1 protocol.
8. Law conversion rule varies depending on the kind of outgoing trunk/terminal and incoming trunk/terminal
in the office where the law conversion is activated. See Table 5-1.
Note 1:Follows the system data assignment (SYS1, INDEX64, b0: 0/1=µ-law/A-law).
Note 2:Non-conversion except when the ISDN terminal interface specification is assigned as N-ISDN1 by the
system data assignment (In this case, the output Layer 1 protocol is fixed as µ-law).
Note 3:Varies depending on the terminal type.Table 5-1  Reference: Output Layer 1 Protocol
