With the introduction of 2.8 release, MikroTik RouterOS supports wide range of Sangoma
Technologies WANPIPE cards. These cards provide a router with the ability to communicate over
T1, E1, RS232, V.35 and X.21 links directly, without the need of external CSU/DSU equipment.
Property Description
active-channels ( all | integer ; default: all ) - for T1/E1 channels only. Specifies active E1/T1
channel set
chdlc-keepalive ( time ; default: 10s ) - Cisco-HDLC keepalive interval in seconds
clock-rate ( integer ; default: 64000 ) - internal clock rate in bps
clock-source ( internal | external ; default: external ) - specifies whether the card should rely on
supplied clock or generate its own
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
frame-relay-lmi-type ( ansi | ccitt ; default: ansi ) - Frame Relay Line Management Interface
Protocol type
framing mode ( CRC4 | D4 | ESF | ESF-JAPAN | Non-CRC4 | Unframed ; default: ESF ) - for
T1/E1 channels only. The frame mode:
• 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
• Non-CRC4 - plain Cyclic Redundancy Check
• Unframed - do not check frame integrity
line-build-out ( 0dB | 7.5dB | 15dB | 22.5dB | 110ft | 220ft | 330ft | 440ft | 550ft | 660ft | E1-75 |
E1-120 ; default: 0dB ) - for T1/E1 channels only. Line Build Out Signal Level.
line-code ( AMI | B8ZS | HDB3 ; default: B8ZS ) - for T1/E1 channels only. Line modulation
method:
• AMI - Alternate Mark Inversion
• B8ZS - Binary 8-Zero Substitution
• HDB3 - High Density Bipolar 3 Code (ITU-T)
line-protocol ( cisco-hdlc | frame-relay | sync-ppp ; default: sync-ppp ) - line protocol
media-type ( E1 | T1 | RS232 | V35 ; default: V35 ) - the hardware media used for this interface
mtu ( integer ; default: 1500 ) - Maximum Transmission Unit for the interface
name ( name ; default: sangomaN ) - descriptive interface name
