| The invention can process the ISDN signaling to select ATM connections and then interwork the ISDN connections with the selected ATM connections. |
| No, and anyway the national root domains could if necessary interwork without them. |
| Nevertheless, the early units from the various manufacturers refused to interwork. |
| Support for industry standards makes it easy to deploy convergence across the organization and interwork with standards-based network elements. |
| And since they interwork with other Nortel key and PBX systems and with our portfolio of convergence call servers, you have a smooth migration path to pure IP solutions. |
| There are several domains in EPS, each one a grouping of logical nodes that interwork to provide a specific set of functions in the network. |
