12. Following parameters can be assigned on a Location basis. The Location is a kind of group (similar
to Tenant in a PBX) that is defined for bandwidth management and parameter settings for LAN
traffic based on the location of IP terminals. Maximum 64 Location numbers can be assigned per
system.
Options Per Location
Type of Codec selection list DiffServ
Type of Service (ToS) Setting Area/Country
Operation when over usable
bandwidth threshold.
PAD control pattern IP-PAD Group number Jitter buffer
Echo canceller-ON/OFF Usable Bandwidth
13. When the IP adapter unit is attached with a Dterm Series E/Series i terminal, other optional
adapters (except for AD/DC adapter unit) cannot be attached with the Dterm Series E/Series i
terminal.
14. Dynamic Host Configuration Protocol (DHCP) cannot be used to assign an IP address to an MP.
15. Login is restricted in following conditions.
When designating a non-existent station number.
("Unregistered" is displayed on the LCD.)
When designating a station number that is not assigned to Multiline Terminal.
("Illegal LEN" is displayed on the LCD.)
16. Logout should be allowed by a station class of service. If not allowed, reorder tone will be heard and
"Restrict" will be displayed on the LCD.
17. Intranet to support Quality of Service (QoS) is preferable to connect IP Stations, to reduce the delay
of connection and voice, and the inferior grade of voice quality.
18. IP Stations operate on 10 Mbps or 100 Mbps LAN based on IEEE 802. (100Mbps LAN is
recommended.)
19. IP Stations support Dynamic Host Configuration Protocol (DHCP). (External DHCP server is
required.)
20. Network-based DRS (external DRS) 3.0 is not supported.
21. Switching hub(s) are required.
22. Spanning Tree (IEEE 802.1d) function is not available.
23. LACP (Link Aggregation Control Protocol, IEEE 802.3ad) function is not available.
24. The
U NIVERGE NEAX 2000 IPS can configure the speed mode of the LAN interface for MP/IP-PAD
card, in addition to Auto Negotiation (default).
The speed mode for the MP card can be set to 100 Mbps full duplex in system data
programming. System initialization is required for the mode to take effect.
The speed mode for the 32IPLA/32IPLA-A card can be set to 100 Mbps full duplex, 100 Mbps
half duplex, or 10 Mbps half duplex, using the rotary switch on the card. The card initialization is
required for the mode to take effect.
The speed mode for the 8IPLA card can be set to 100 Mbps full duplex using the DIP switch on
the card. The card initialization is required for the mode to take effect.
25. When the QoS Display function key is pressed on IP Enabled Dterm, the QoS information (number
of lost packets, codec type and payload size) is displayed.
A function key on IP Enabled Dterm should be assigned as QoS Display key in system data
programming.
No other LCD information from PBX such as Clock/Calendar, calling station number and name
is displayed during QoS display.
To stop QoS display, press the EXIT soft key (not EXIT button). Even if the call ends and the
Dterm user goes on-hook, the QoS display remains unless pressing the EXIT soft key.
