Description

You can install up to four Cyclades PC300 PCI Adapters in one PC box, if you have so many adapter slots and IRQs available.

The Cyclades PC300/RSV Synchronous PCI Adapter comes with a V.35 cable. This cable should work for all standard modems, which have V.35 connections. For synchronous modems, which have a DB-25 connection, you should use a standard DB-25 cable.

Connect a communication device, e.g., a baseband modem, to the V.35 port and turn it on. The MikroTik driver for the Cyclades Synchronous PCI 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.

Property Description

name (name; default: cycladesN) - assigned interface name
mtu (integer; default: 1500) - Maximum Transmission Unit
line-protocol (cisco-hdlc | frame-relay | sync-ppp; default: sync-ppp) - line protocol
media-type (E1 | T1 | V24 | V35 | X21; default: V35) - the hardware media used for this interface:
clock-rate (integer; default: 64000) - internal clock rate in bps
clock-source (external | internal | tx-internal; default: external) - source of the clock
line-code (AMI | B8ZS | HDB3 | NRZ; default: B8ZS) - for T1/E1 channels only. Line modulation method:
  • AMI - Alternate Mark Inversion

  • NRZ - Non-Return-To-Zero
    framing-mode (CRC4 | D4 | ESF | Non-CRC4 | Unframed; default: ESF) - for T1/E1 channels only. The frame mode:
  • Unframed - do not check frame integrity
  • Non-CRC4 - plain Cyclic Redundancy Check
  • CRC4 - Cyclic Redundancy Check 4-bit (E1 Signaling, Europe)
  • D4 - Fourth Generation Channel Bank (48 Voice Channels on 2 T-1s or 1 T-1c)
  • ESF - Extended Superframe Format
    line-build-out (0dB | 15dB | 22.5dB | 7.5dB; default: 0) - for T1 channels only. Line Build Out Signal Level
    rx-sensitivity (long-haul | short-haul; default: short-haul) - for T1/E1 channels only. Receiver sensitivity
    active-channels (multiple choice: integer; default: all) - for T1/E1 channels only. Numbers of active channels (up to 32 for E1 and up to 24 for T1)
    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 TE models
    frame-relay-lmi-type (ansi | ccitt; default: ansi) - Frame Relay Line Management Interface Protocol type

    RSV/V.35 Synchronous Link Applications

    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:

    MT-to-CISCO

    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            NETWORK         BROADCAST       INTERFACE

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

    received: 50
     min-rtt: 1
     avg-rtt: 1
     max-rtt: 9

[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 the 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
    #    DST-ADDRESS        G GATEWAY         DISTANCE INTERFACE
    0  S 0.0.0.0/0          r 1.1.1.2         1        cyclades1
    1 DC 10.0.0.0/24        r 0.0.0.0         0        ether1
    2 DC 192.168.0.0/24     r 0.0.0.0         0        ether2
    3 DC 1.1.1.2/32         r 0.0.0.0         0        cyclades1
[admin@MikroTik] ip route>

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

    CISCO#show running-config

Current configuration:

    Send ping packets to the MikroTik router:

    CISCO#ping 1.1.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
