Description

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 setchdlc-keepalive (time; default: 10s) - Cisco-HDLC keepalive interval in secondsclock-rate (integer; default: 64000) - internal clock rate in bpsclock-source (internal | external; default: external) - specifies whether the card should rely on supplied clock or generate its ownframe-relay-dce (yes | no; default: no) - specifies whether the device operates in Data Communication Equipment mode. The value yes is suitable only for T1 modelsframe-relay-lmi-type (ansi | ccitt; default: ansi) - Frame Relay Line Management Interface Protocol typeframing 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
