Fast Track Guide 3. Configuring the Mediant 1000
Version 5.0 17 October 2006
¾ To configure basic MEGACO parameters, take these 16 steps:
1. If your network features a DNS server, in the ‘DNS Primary Server IP’ and ‘DNS Secondary
Server IP’ fields, enter the primary and secondary DNS servers' IP address (clarify with your
network administrator).
2. If your network features a DHCP server, from the ‘Enable DHCP’ drop-down list, select
‘Enable’; the ‘IP Address’, ‘Subnet Musk’, and ‘Default Gateway IP Address’ fields are
disabled. When the gateway is configured for DHCP, it attempts to contact the DHCP server
to obtain networking parameters (e.g., IP address, subnet mask, default gateway, and
primary/secondary DNS server).
3. Under the ‘Trunk Configuration’ group, select the ‘Protocol Type’ you use. Note that the
Trunk Configuration parameters are global, and apply to all trunks. To configure different
parameters per trunk, refer to Section 3.6 on page 25.
4. In the ‘Framing Method’ field, select the ‘Framing Method’ you use (for E1 trunks, always set
the Framing Method to ‘Extended Super Frame’).
5. From the ‘Clock Master’ drop-down list, select the trunk clock source. Choose either
‘Recovered’ (the clock is recovered from the trunk; default) or ‘Generated’ (the trunk’s clock
source is provided by the internal TDM bus clock source, according to the parameter ‘TDM
Bus Clock Source’). For detailed information on the parameter ‘TDM Bus Clock Source’,
refer to the Mediant 1000 MEGACO User’s Manual.
6. From the ‘Line Code’ drop-down list, select the Line Code: ‘B8ZS’ (bipolar 8-zero
substitution) only for T1; ‘HDB3’ (high-density bipolar 3) for E1; ‘AMI’ (alternate mark
inversion) for both E1 and T1 spans.
7. From the ‘ISDN Termination Side’ drop-down list (only for ISDN protocols), select ‘User Side’
when PSTN or PBX is configured as ‘Network side’ and vice versa. If the Mediant 1000 ISDN
termination side is unknown, choose ‘User Side’, then navigate to the ‘Alarms’ screen by
clicking the Home button. If the D-channel alarm is indicated, choose ‘Network Side’.
8. In the ‘Control Protocol Type’ field, select the control protocol type you use.
9. In the ‘Call Agent IP’ field, enter the Call Agent IP address if your enterprise’s network
doesn’t feature a DNS server that automatically defines the Call Agent’s IP address.
10. In the ‘Call Agent Port’ field, enter the Call Agent port. The default port is 2944.
11. In the ‘Call Agent Domain Name’ field, enter the Call Agent domain name. When using DNS
server, enter the domain name of the Call Agent operating with the Mediant 1000. The DNS
server automatically detects the Call Agent’s IP address from the domain name.
12. In the ‘Physical Name Pattern’ field, enter an intuitive name to identify the gateway’s physical
termination in the format: [name1]*[name2]*. The first asterisk represents the number of the
trunk; the second asterisk represents the number of the endpoint. For example, ‘tgw/t*/c*’.
13. In the ‘Logical RTP Name Pattern’ field, enter an intuitive name to identify the gateway’s
RTP termination in the format: [name]*. The asterisk represents an internal identification
assigned by the gateway to the RTP termination. For example, 'gw/rtp/*'.
14. In the ‘Logical ATM Name Pattern’ field, enter an intuitive name to identify the gateway’s
ATM termination (if used) in the format: [name]*. The asterisk represents an internal
identification assigned by the gateway to the ATM termination. For example, 'gw/atm/*'.
15. Click Reset, and then click OK; the Mediant 1000 applies the changes and restarts.
16. After the gateway is reset, if different configuration is required per trunk, refer to Section 3.6
on page 25. Otherwise, set the ‘PCM Law Select’ field (Advanced Configuration > TDM
Bus Settings), select ‘A-law’ for E1 trunks and ‘µ-Law’ for T1 trunks.
Note: For MEGACO users, continue with Section 3.6 on page 25.
