SDLC & Network configuration Help?

Help?

I have a customer in the process of swapping their Motorola routers
(on Sprint Frame Relay) out in favor of Ciscos. Sprint is providing
the equipment and now are asking a question I can't seem to answer.

Here is the Configuration as it now stands.

Main Office:
    AS/400
        Serial Port with SDLC for Area office #1
        Serial Port with SDLC for Area Office #2
        Ethernet port

    Area Office #1
        AS/400
            Serial Port with SDLC to Main Office
            Perle 494 Serial Port with SDLC to Main Office (5
cards/controllers)
        Ethernet Lan

    Area Office #2
        Perle 494 Serial Port with SDLC to Main Office (2
cards/controllers)
        Ethernet Lan

The Main Office AS/400 serial ports plug directly into the router. The
Ethernet obviously goes to a hub for the LAN and then to the hub. Area
Office #1 AS/400 and Perle serial ports plug directly into the router.
They are changing the router to add the Ethernet connection. Area
Office #2 Perle serial plugs directly into the router and the LAN has
a cable from the hub to the router.

Specifically the Area Office #1 AS/400 and the Perle appear to the
Main Office AS/400 as a multi-drop lease line separate from Area
Office #2.
Area Office #2 Perle appears as another multi-drop lease line.

The Perles do not appear to have an exchange ID. However the AS/400's
do. The main office AS/400 has the same exchid on both line
descriptions. The Area Office #1 has a different exchid in the
controller and its actual config devices have the swap between line
and controller exchids.

All three sites will have the Ethernet LANs tied together to access
the Main Office AS/400.

Sprint is asking "What is the MAC address of the serial ports?"

I've never heard of a MAC for SDLC. Does anyone know how to determine
this or have a Sprint contact that I can get our Sprint contract to
talk to?

Thanks.
