CBUQBR User Manual80-14004000-013–2for B2. The best practice is fill in the last complete number block, forexample in the UK the last 6 digits (or 7 digits for city numbers). Thenumber entered is also used for dialling additional aggregation callswhen using the CBUQHS.• If any port is not connected to the network then it must have its lineconfiguration deleted for both ‘B’ channels. Any ports can bedisconnected, providing the Line Configuration menu reflects this.• The Routing menu (under Configuration top menu) must beconfigured to assign user port cards, e.g. CBUQHS or CBUQLS, andtheir respective ports. If the line is an MSN type or single numberedsub-address type, the desired MSN or sub-address numbers must beentered in the Set MSN and Set Subaddress sub-menus. (The‘Record’ number is simply a numbered list and its number has norelation to port numbering, card slot numbering or ‘B’ channelnumbering).• When using with the CBUQHS one extra ‘B’ channel is required forsynchronisation purposes in addition to the number of ‘B’ channelsrequired for user port speed aggregation. For example for a 448kbit/scall, seven ‘B’ channels are required for data plus one forsynchronisation, thus requiring 8 ‘B’ channels - all four BRI lineswhich is the maximum. 512k aggregation is not possible with aCBUQBR.3.2.2 Suggested Configuration MethodThe following is a tried and proven method of configuring the CBUQBR,in the following order:-1. Plug in the BRI lines into the CBUQBR, making a note of all the linenumbers versus CBUQBR ports.2. Go to the Line configuration menu and enter each line numberagainst the Primary and Secondary entries, for all ports connected tolines. The ‘Primary’ entry is the B1 number and ‘Secondary’ entry isthe B2 number. For an MSN line, enter the desired MSN number,e.g. Primary 123451, Secondary 123452 (assuming a base number of123450, with a possible number range of 123450-123459). For asingle numbered line, enter the same number for both Primary andSecondary entries. |
