The MikroTik driver for the MOXA C101 Synchronous adapter allows you to unplug the V.35 cable from one modem and plug it into another modem with a different clock speed, and you do not need to restart the interface or router.
[admin@MikroTik] interface> moxa-c101
[admin@MikroTik] interface moxa-c101> print
Flags: X - disabled, R - running
0 R name="moxa-c101-1" mtu=1500 line-protocol=sync-ppp clock-rate=64000

You can monitor the status of the synchronous interface:
[admin@MikroTik] interface moxa-c101> monitor 0
dtr: yes
rts: yes
cts: no
dsr: no
dcd: no
[admin@MikroTik] interface moxa-c101>
Connect a communication device, e.g., a baseband modem, to the V.35 port and turn it on.
If the link is working properly the status of the interface is:
[admin@MikroTik] interface moxa-c101> monitor 0
dtr: yes
rts: yes
cts: yes
dsr: yes
dcd: yes
[admin@MikroTik] interface moxa-c101>
Let us consider the following network setup with two MikroTik Routers connected to a leased line with baseband modems:
The driver for MOXA C101 card should be loaded and the interface should be enabled according to the instructions given above. The IP addresses assigned to the synchronous interface should be as follows:
[admin@MikroTik] ip address> add address 1.1.1.1/32 interface wan \ \... network 1.1.1.2 broadcast 255.255.255.255 [admin@MikroTik] ip address> print Flags: X - disabled, I - invalid, D - dynamic # ADDRESS NETWORK BROADCAST INTERFACE 0 10.0.0.254/24 10.0.0.254 10.0.0.255 ether2 1 192.168.0.254/24 192.168.0.254 192.168.0.255 ether1 2 1.1.1.1/32 1.1.1.2 255.255.255.255 wan [admin@MikroTik] ip address> /ping 1.1.1.2 1.1.1.2 64 byte pong: ttl=255 time=31 ms 1.1.1.2 64 byte pong: ttl=255 time=26 ms 1.1.1.2 64 byte pong: ttl=255 time=26 ms 3 packets transmitted, 3 packets received, 0% packet loss round-trip min/avg/max = 26/27.6/31 ms [admin@MikroTik] ip address>The default route should be set to the gateway router 1.1.1.2:

The configuration of the Mikrotik router at the other end is similar:

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 MOXA C101 card should be loaded and the interface should be enabled according to the instructions given above. The IP addresses assigned to the synchronous interface should be as follows:

The configuration of the CISCO router at the other end (part of the configuration) is:
