5 • DS0 Mapping '6/'$&6$GPLQLVWUDWRUVª5HIHUHQ H*XLGH40 'LVSOD\LQJWKH'60DSSLQJZLQGRZ'HYLH 6ORWVThe "slots" input identifies the DS0 channels—each DS0 channel is 64 kbps—that you would like to con-nect. Each iDSL modem has up to 2 DS0 channels and 1 16 kbps channel. Each time slot in a T1 or E1 WANport has 24 or 31 DS0 channels, respectively. When selecting the slots you must select the same number ofslots on the "A" and "B" side of the connection. The slots are selected by entering a string that represents theslots. For the iDSL ports, the slots that are available are 1 and 2. (In certain 144Kbps setups you may also selectslot 3.) For a WAN port configured as a T1, the available slots are numbered from 1 - 24. For a WAN portconfigured as an E1, the available slots are 1 - 31. The following notation should be used for entering the slots.Several examples are given below.• dash: (-) 1 - 4• comma: (,) 1,4,9• combo: 1 - 2, 3,6 - 7For example, to connect a T1 Port using timeslots 1,2, 5, 6, 7, and 15, you can input any of the followingstrings:1,2, 5-7, 151 - 2, 5,6,7,151 - 2, 5 - 6, 7, 15ConfigurationThe user can make connections in the box using two different methods. The easiest way is by using the pulldown windows provided. But the user can also add connection using the command line format by entering atext string. To input a static connection into the box using the text string. Use the following convention:• DeviceA:PortA:SlotsA/DeviceB:PortB:SlotsBDevice Options - The interface that you would like to select1) t1-e12) iDSLPort Options - The Port Number (starting at 1) may be one of the four WAN ports or one of the 24 iDSLmodems. To configure Slots (DS0 channels), choose the slots that you would like to use. The followingnotations are allowed:1) dash (-): 1 - 42) comma (,): 1,4,93) combination of dashes and commas: 1 - 2, 3,6 - 7Example #1: To connect a T1 line, (WAN) Port 1, timeslots 1 and 2 to an iDSL modem, Port 3 (modem#3), timeslots 1,2, input the following string:t1-e1:1:1 - 2/iDSL:3:1 – 2Example #2: To connect a T1 line, (WAN) Port 2, timeslots 4 – 6, to another T1 line, (WAN) Port 3,timeslots 8 – 10, input the following string:t1-e1:2:4 – 6/t1-e1:3:8-10
