Can you combine a PRI circuit and a T1/D4 circuit on the same Dual T1/E1 Framer card, or do they need to be the same on both ports? I know that you couldn't mix them up on a NSU, but does that same rule apply here. In the Tech Handbook 6.0 page 179, the writing is confusing to say the least - see below.
Dual T1/E1 Framer
• Each Dual T1/E1 Framer has 2 ports (RJ-45 connectors), each of
which can be used for T1/E1 ISDN or T1/D4. The two protocols can
operate in tandem on the same Dual T1/E1 Framer with any ISDN
variant, i.e. PRI and QSIG.
• T1/D4 provides for digital E&M, digital DID, or digital CO protocols.
T1/E1 ISDN provides for DMS-100, DMS-250, NI-2 (Bellcore National
ISDN, 5ESS, GTD5), Euro ISDN, 4ESS, Euro-ISDN (CTR4), HKIDAP,
and QSIG protocols.
Any clarification on this would be greatly appreciated.
