Detailed explanations of PVC options are follows:
broadcast: Forward broadcast packet to the peer PVC.
encapsulation-type: Encapsulation type, which may be nonstandard, ietf,
multi-protocol and snap.
packet-size input-packet output-packet: Specifies the maximum receiving
packet length and maximum sending packet length. The length is counted in
byte, which must range from 16 to 4096 (including 16 and 4096), and must be
the integer power of 2.
window-size input-window-size output-window-size: Specifies the receiving
window and transmitting window sizes of the VC, which range between 1 and
the number that is 1 less than the modulus of the X.25 interface where the
address mapping exists (including 1 and modulus minus 1).

channel section, and set two VCs.
