chdlc-keepalive ( time ; default: 10s ) - Cisco-HDLC keepalive interval in seconds
frame-relay-dce ( yes | no ; default: no ) - specifies whether the device operates in Data
Communication Equipment mode. The value yes is suitable only for T1 models

Description
• The cyclades interface does not show up under the interfaces list
Obtain the required license for synchronous feature
• The synchronous link does not work
Check the V.35 cabling and the line between the modems. Read the modem manual

RSV/V.35 Synchronous Link Applications

Example
Let us consider the following network setup with MikroTik Router connected to a leased line with
baseband modems and a CISCO router at the other end:
The driver for the Cyclades PC300/RSV Synchronous PCI Adapter should load automatically. The
interface should be enabled according to the instructions given above. The IP addresses assigned to
the cyclades interface should be as follows:
[admin@MikroTik] ip address> add address=1.1.1.1/32 interface=cyclades1
[admin@MikroTik] ip address> print
Flags: X - disabled, I - invalid, D - dynamic
# ADDRESS
0 10.0.0.219/24
1 1.1.1.1/32
2 192.168.0.254/24
[admin@MikroTik] ip address> /ping 1.1.1.2
1.1.1.2 64 byte pong: ttl=255 time=12 ms
1.1.1.2 64 byte pong: ttl=255 time=8 ms
1.1.1.2 64 byte pong: ttl=255 time=7 ms
3 packets transmitted, 3 packets received, 0% packet loss
round-trip min/avg/max = 7/9.0/12 ms
[admin@MikroTik] ip address> /tool flood-ping 1.1.1.2 size=1500 count=50

[admin@MikroTik] ip address>
Note that for the point-to-point link the network mask is set to 32 bits, the argument network is set
to the IP address of the other end, and the broadcast address is set to 255.255.255.255. The default
route should be set to gateway router 1.1.1.2:
[admin@MikroTik] ip route> add gateway 1.1.1.2 interface cyclades1
[admin@MikroTik] ip route> print
Flags: X - disabled, I - invalid, D - dynamic, J - rejected,
C - connect, S - static, R - rip, O - ospf, B - bgp
