After issuing the following commands :-

#ngctl mkpeer sync_ar0: frame_relay rawdata downstream
#ngctl mkpeer sync_ar0:rawdata lmi dlci0 ansi
#ngctl mkpeer sync_ar0:rawdata rfc1490 dlci16 rfc1490
#ngctl mkpeer sync_ar0:rawdata dlci16 rl0 inet inet
#ifconfig ng0 1.2.3.4 5.6.7.8
ifconfig: interface ng0 does not exist

The command ifconfig shows :-

rl0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    options=8<VLAN_MTU>
    inet6 fe80::207:40ff:fe09:f09%rl0 prefixlen 64 scopeid 0x1

    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x5
    inet 127.0.0.1 netmask 0xff000000

and the command "ngctl list" shows :-

There are 4 total nodes:
  Name: ngctl811        Type: socket          ID: 00000011   Num hooks: 0
  Name: <unnamed>       Type: frame_relay     ID: 00000004   Num hooks: 1
  Name: sync_ar1        Type: sync_ar         ID: 00000002   Num hooks: 0
  Name: sync_ar0        Type: sync_ar         ID: 00000001   Num hooks: 1

Would it be the problem that I test it with cable disconnected from the 
modem (i.e.CSU/DSU)?

Thanks a lot.
