Please help with this. I am new with TC. It is possible to use E1 PRI lines with TC 1000 when I have T1 modems. I have this configuration: 5 3Com High-Density 24 Channel DSP (120 lines) 5 3Com T1/E1 HDM DSP NIC's 2 Hiper Acces Router Card 1 Hiper NMC 2 AC PSU 130 AMP Nac 1 10/100 NMC NIC 2 Dual 10/100 PCI Ethernet NIC Can I address the 24 modems in the T1 DSP to make it work with the E1s? Something like use 4 E1s (120 lines) map the 5 T1 modem cards (120 modems). Thank you for your help. Jaime
