| Clock Master/ Emulation: |
The network side should be configured as an "NT", and the clock should be provided |
| Framing: |
CRC-4 multiframing recommended |
| Line coding: |
HDB-3 |
| Physical Interface: |
120 Ohm or 75 Ohm (also known as 'unbalanced coax'); if your interface is RJ48, then it is 120 Ohm, if it is a coax connection, then it is 75 Ohm (Dialogic supplies a 75 to 120 Ohm converter if your network termination is 75 Ohm) |

| Channel Service: |
64Kbps clear channel service end-to-end for every call |

| B Channel ID for Outgoing Calls: |
The Brooktrout board exclusively decides on which B channel an outgoing call will proceed |
| Compatible Switch Types: |
Generic ITU-T compliant |
| In case you need Inbound Routing : |
Please verify with your telco people that you are receiving a called party number.
In order to receive the digits properly, you will typically have the following callctrl.cfg settings:
reject_incomplete FALSE max_did_digits 20 did_timeout 5 |
Additional Information:
- Preferably, you want layers 1 and 2 kept active
- Please do not ask for a specific HLC, eg "telephony"
