 | | Trunk & Leased-line Products
| |
The trunk and leased-line products allow one to access PSTN through a bundle of telephone lines (e.g. PRI ISDN with 28 user lines via an E1 leased line) as well as establish point-to-point connection for users which need transfer data between two points. Data rates from 64kbps to E1 (2Mbps) are available. Typical application is also connecting between two or more LANs of branch offices and ISPs who need dial-up connectivity for their customers via the PTT.
 | Analog line
| | The analog line product uses available wire connections which are impossible to convert into ISDN lines. Maximum transmission rate represents 33,6kbps. For Internet access can be used K56-FLEX or V.90, V92 Standards for 56kbps downloads and 33,6kbps upload.
| | ISDN line
| | The ISDN line product is used by all wire connected users where the line quality allows the use of ISDN adapters and in this way use transmission rates 64kbps or 128kbps.
| | PRI line
| | The PRI line is dedicated for users which need to access the PSTN with more than 6 telephone lines. In special cases it can be used for connecting between two ISDN PABX, i.e., a point-to-point connection. Standard transmission rate is 2Mbps (E1) standard) with dedicated 28 ISDN, user-addressable lines (28 phone numbers) and 2 control lines (used for SS7 signaling and synchronization). Per request we can alter this line to the reduced transmission rate of a T1 (1,544Mbps), i.e., 18 addressable telephone lines and 2 control lines.
| | E1 line
| | The E1 line represents European standard for communication on low-level trunk lines. Generally it is available as a fractional E1 as well as multiple E1 data rates. The fractional E1 with 64kbps step is reasonable for applications where in the future the transmission rate is expected to rise (no additional costs necessary). In the cases where E1 does not satisfy the customer requirements, we can augment the capacity up to 8xE1 = 16Mbps transmission rate. | |
