Front panel user interface > Codec/Transmission 43 3.2.3.1.1 Ethernet Here the IP settings can be done for internal electrical network card of C11. For C1191 Advanced Dual IP Codec the IP settings can be done for both Ethernet interfaces separately. The following parameters can be set: a) DHCP DHCP (= Dynamic Host Configuration Protocol) enables C11 to configure its IP-settings (except SIP) automatically with help of a DHCP server. To enable DHCP set this parameter to 'client'.
Front panel user interface > Codec/Transmission should be bigger than average network jitter (see Codec/Status/Interface) Note 2: If AJC is activated the delay value set here will be added to the value measured by AJC (see System/Misc/AJC) g) SIP (Session Initiation Protocol) - configures all the parameters of SIP session. Globalproxy This field allows a global SIP proxy to be set. This can be used to force all SIP messages to pass through a certain server.
Front panel user interface > Codec/Transmission 45 Account Registrar The Registrar is the SIP registration server which resolves the SIP address to a real IP address. The SIP client must register itself to a Registrar first before it can use its service. In this field an IP address or a URL can be entered. The registration comprises the following access data: - Name - Password - Phone Number (not always necessary) Account Phonenr Here the phone number of the registration access data can be entered.
Front panel user interface > Codec/Transmission MSN (= Multiple Subscriber Number) In this field the MSN (D-channel protocol DSS1 or VN4) or the ID (all other Dchannel protocols) is entered. The most common reason to use MSN are: · Multiple ISDN devices using the same ISDN service uses one ISDN bus (e.g.
Front panel user interface > Codec/Transmission 47 Active layer 1 mode - determines whether ISDN Layer 1 stays active all the time, or not. When C11 is used in the Netherlands, this value should definitely be set to ON. Answer time - defines the ‘telegram’ interval (used in ISDN connections) - in milliseconds. The called MAYAH codec sends out its ‘telegram’ 10 times till the ISDN answer delay expires. The default value is 5,000 ms.

Front panel user interface > Codec/Transmission more packets can be resorted. Generally receive buffer value should be bigger than average network jitter (see Codec/Status/Interface) Due to the usually very limited bandwidth at POTS connections the most efficient MPEG-4 HE-AACv2 (AAC HE) stereo is used by C11, no matter which Codec Quality has been chosen previously. C11 evaluates the quality of current connection and adjusts the bit rate automatically. 3.2.3.1.
