Full text: VPNにおける対向拠点は最大1000対地（拡張メモリ搭載時）、ISDN同時接続可能な対向拠点は46対地（PRI拡張モジュール×2搭載時）と、大規模なネットワークの集線に対応しています。
My understanding: There is a maximum of 1000 tunnels at the opposite VPN end-point (with extended memory installation), at the same time the possible ISDN end-point connections are at 46 tunnels (with 2 PRI extended module installations), supporting large-scale network hub/concentrator.
My Issue: 集線. I understand that it is a networking connection device. Does it mean a hub or concentrator?
集線 is not a device name but an action name (i.e., suru-verb) that means 集 ("aggregating", "assembling", "collecting") + 線 ("cable", "line").
Note that と before this part is not "and" but this "content-descriptor" と. Thus, this 集線 refers to what this router can achieve by connecting to many endpoints. The device that does only 集線 is called a hub (e.g. an USB hub), but a router can do 集線, too.
…と、大規模なネットワークの集線に対応しています。
..., thus enabling/realizing a large-scale network concentration.
